Made from BK7 material, which has transparent range from 330-2100nm. The refractive index is 1.5168 at 587.6nm. The BK7 window has good performance over visible and near IR spectrum for most application.
Achromatic Waveplate Achromatic Waveplates(Retarders), AWP is composed of one piece of Crystal Quartz and one piece of Magnesium Fluoride, MgF2.
Barium fluoride (BaF2) shows good optical transmission over UV-IR windows in 0.15μm~12.5μm.
MgF2 windows are used in the UV, visible and IR ranges, with approximately 94% transmission from 200 - 1000 nm, and approximately 95% transmission from 1-6µm
CaF2 has transparent range from 170-7800nm. The refractive index is 1.399 at 5000nm. 1. Low absorption coefficient 2. High damage threshold, 3. Low Dispersion (with an Abbe Number of 95) 4. Low fluorescence 5. Excellent water, chemical, and heat resistance
Zero order waveplate are constructed of two multiple order waveplates which is designed to give a retardance of zero full waves, plus the desired fraction.
1. Zero Order Waveplates-Cemented by Epoxy
2. Zero Order Waveplates-Optically Contacted
3. Zero Order Waveplates-Air-spaced

Zero order waveplates are constructed of two multiple order waveplates with their axes crossed, thus the effect of the first plate is cancelled by the second, except for the residual difference between them. The two multiple order waveplates can be glued together or optically contact.
Zero order waveplates are much less susceptible to wavelength changes, can be up to 2% above or below the design wavelength with little effect on retardation. The waveplates should be considered for more critical application.
Damage threshold is about 100MW/cm2.
There are three contact way.
1. Cemented by Epoxy (AR Coated, R<0.2%, Better Temperature Bandwidth
2. Optical Contacted (AR Coated,R<0.2%, High Damage Threshold, Better Temperature )
3. Air-spaced (AR Coated,R<0.2% and Mounted, High Damage Threshold, Broad Temperature Bandwidth)

L-bar Mini Prism mounted in metal holder. Supplied with L-bar for fixed installations. The prism offset is dependant on the mounting position,range 2000 m
Right Angle Prism is deviating or deflecting a beam of light with 90°or 180°. It is often used in telescope, periscope and other optical system. Deviate Beam or Image by 90° or 180° Material: N-BK7, UV Fused Silica, CaF2, ZnSe, or Ge AR-Coated, HR coated are Available
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).It's a negative uniaxial crystal and mostly used as visible and near IR polarizers. It has high birefringence, wide spectral transmission and availability in reasonably sized rhombs.
Selective Absorption Colored Glass Filters This part of the glasses can be divided into 14 kinds and 78 types based on the color and application in this catalogue.
Schmidt Prisms Schmidt prisms are used to invert and revert an image to angle of 45°. The 45° deviation makes Schmidt prisms useful in eyepiece assemblies and imaging systems requiring a path bend. 1. Ray Deviation of 45° 2. Right Handed Image 3. Combine with Half-Penta Prism to Create Pechan Prism
