Brewster Windows |
| DESCRIPTION |
Brewster Windows are uncoated substrates used as polarizers, typically within a laser cavity. Positioned at Brewster's Angle (see calculation below) the P-Polarization portion of the light will pass through the window with no losses while the S-Polarization portion will be reflected off the brewster window. Used in a laser cavity the brewster window is essentially a polarizer.
Brewster's Angle is calculated from:
B = tan-1(n)
where B is Brewster's Angle and n is the index of refraction of the material.

Lyot Depolarizers |
| DESCRIPTION |
Depolarizers are used where a linearly polarized light is undesirable such as with polarization sensitive devices. The depolarizer converts the polarized input into a pseudo-randomly polarized output. Our depolarizers are optically contacted and AR coated for high power operation. Lyot depolarizers consist of two quartz waveplates one being exactly twice the thickness of the other and assembled with their optic axes 45° apart. This combination creates various degrees of elliptical polarization as a function of wavelength and therefore, Lyot depolarizers cannot be used with monochromatic beams. |

Wedge Depolarizers |
| DESCRIPTION |
Depolarizers are used where a linearly polarized light is undesirable such as with polarization sensitive devices. The depolarizer converts the polarized input into a pseudo-randomly polarized output. Our depolarizers are optically contacted and AR coated for high power operation. A variation in retardance across the aperture is created by the wedge-shaped crystalline quartz optic to scramble the polarization. A fused silica wedge is cemented to the quartz wedge to compensate for beam deviation. Wedge depolarizers are achromatic and can be used with any input beam. |

Fresnel Rhomb |
| DESCRIPTION |
Unlike quartz waveplates, Fresnel rhombs are inherently less sensitive to wavelength (i.e. achromatic) since the phase shift is a function of the glass index which varies only slightly over the design wavelength range. The wavelength varies less than +/-2% over a range from 600nm to 1550nm. Each Fresnel rhomb is designed for a l/4 wave retardance. The l/2 wave rhombs use two l/4 rhombs cemented together. We can also manufacture UV rhombs as well as air-spaced rhombs for high power applications. |

True Zero Order |
| DESCRIPTION |
Our true zero order waveplates are precision polished to a zero order retardance thickness. This results in a waveplate with the least sensitivity to wavelength, temperature, and angle of arrival. The thickness of a waveplate is determined by the desired retardance, operating wavelength, and the birefringence of the material. A true zero order quartz waveplate is typically very thin (i.e. quarter wave at 633nm is only 17.5μm thick). However, due to the change in birefringence with wavelength, a practical thickness can be achieved only at longer wavelengths. We offer l /2 and l /4 wave true zero order waveplates at the popular telecom wavelength, 1550nm (note: the l /4 wave can be used like a quarter waveplate with a sign reversal). |

Beamsplitter Cubes |
| DESCRIPTION |
Nova Phase offers a full range of 10x10x10mm, 20x20x20mm and 25.4x25.4x25.4mm beam splitting cubes. All of these cubes are designed to provide a 50:50 split ratio and to work over a broad wavelength range. Models are offered for 400-700nm, 700-1100nm and 1100-1600nm operating ranges. The entrance and exit faces are antireflection coated while the diagonal internal surface has the broadband beam splitting coating. These cubes have been optimized for the maximum number of applications by designing them to be polarization independent. By using a cube rather than a coated round optic beam deflection for the through beam is almost completely eliminated. |

EO Modulators |
| DESCRIPTION |
Nova Phase introduces a new line of free-space electro-optic amplitude and phase modulators. We've combined our experience with crystal growth and electro-optic materials to develop a line of lithium niobate modulators that offer both price and performance. Our full bandwidth DC-coupled modulators are directly driven by a user-supplied RF source. Resonant frequency models use an RF tank circuit to boost the signal across the EO crystal to allow full depth of modulation from a standard low voltage function generator.
Our standard modulators use undoped lithium niobate for the electro-optic crystal. For higher power operation, we also offer MgO-doped lithium niobate. |

Compensators |
| DESCRIPTION |
The Soleil-Babinet Compensator is a continuously variable, zero-order retarder (waveplate) which operates over a broad wavelength range. The classical design of the compensator consists of a long birefringent wedge and a fixed wedge mounted to a compensator plate. The retardance is adjusted by moving the position of the long wedge relative to the short wedge using the precision digital micrometer. This allows the retardance to vary continuously while maintaining a uniform retardance across the aperture at any given setting.
The standard Soleil-Babinet Compensators are uncoated for broad spectral operation. To minimize reflection losses when using the compensator over narrow wavelength ranges, AR coated versions are available upon request. |

Reflective ND Filters |
| DESCRIPTION |
These metal coated (Inconel) glass ND filters provide a uniform attenuation over a broad spectral range. The "optical density" is defined by the following equation: ND=log10(1/T), or T=10-ND. The Inconel film is a very hard metallic alloy that is resistant to aging under normal conditions. The Inconel coating will oxidize at elevated temperatures: it is recommended that the ND filters only be used at temperatures below 100°C. |

Glan Taylor |
| DESCRIPTION |
The Glan Taylor Calcite Polarizer provides extremely pure linear polarization (100,000:1) for broadband sources. The input and output faces are polished to a laser quality 20/10 surface finish to minimize scattering of the transmitted P polarization component of the laser beam or light field. The S polarization component is reflected through a 68° angle and exits the polarizer through one of the two side ports; the side ports are pad polished. For high power applications, see our Glan Laser Polarizers. |

Glan Laser |
| DESCRIPTION |
The Glan Laser Calcite Polarizer is a Glan Taylor polarizer that is specifically designed to deal with high energy laser light. These polarizers are manufactured from only select portions of the calcite crystal that pass a sensitivity laser scattering test. Like our Glan Taylor Prisms, these prisms are ideal for applications requiring extreme polarization purity (100,000:1), high damage threshold (500MW/cm2) and a broad wavelength range (250nm-2.3μm). Two polished side exit ports are provided to allow bi-directional use of the prism polarizer. These side ports also ensure that the rejected light from high power lasers can be safely removed from the polarizer. |

Zero Order - Unmounted |
| DESCRIPTION |
Zero Order Waveplates are constructed from two multi-order waveplates that have their fast axes rotated 90 degrees with respect to each other so that the two retardances subtract. The net result is a compound waveplate with a net retardance equal to the difference between the two waveplates. This results in a waveplate that has a spectra bandwidth and temperature bandwidth equivalent to a true zero order waveplate (note: the angle-of-arrival dependency is higher due to the longer optical path). The two waveplates are air spaced and bonded with an epoxy adhesive. All of our waveplates are AR coated with a V-coat at the design wavelength and are available unmounted or mounted in an anodized aluminum 1" mount. |

Achromatic |
| DESCRIPTION |
Nova Phase's bi-crystalline achromatic waveplates are zero-order retarders designed using two different birefringent materials, crystalline quartz and magnesium fluoride, to balance the dispersion and provide a nominally flat spectral response. Each achromatic waveplate is computer designed and optimized for minimum RMS retardance error over a broad spectral range. These achromatic waveplates are air-spaced and have AR coatings on all surfaces for minimal insertion loss and unlike polymer film retarders, Nova Phase's achromatic waveplates can handle high optical powers. |
