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

High Presion Double Concave Lenses and Bi-concave Lenses
Double Concave Lenses, Bi-Concave Lenses is like the Plano-Concave lenses in that they are used to produce divergent light. The Bi-Concave is best used when the input beam is converging. 1. Supported by the Zemax Optical Design Package 2. Negative Focal Length 3. Material upon requirement
Rods Lenses and Light pipes
Rod lenses Light pipes is used in the fields of medical, electronic, information, agriculture, communication and etc. 1.All surfaces (end-faces and cylinder)polished; 2.Only end-faces polished; 3.Only Cylinder polished.
High Reflective Broadband Dielectric Mirrors
