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

Survey Prisms are for Surveying or land surveying is the technique, profession, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them.
Hastings triplets achromatic lenses are designed to provide an infinite conjugate ratio and are useful for focusing collimated beams and for magnification. Steinheil triplets achromatic lenses are designed to provide a finite conjugate ratio and 1:1 imaging.
