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

Optical High Precision Rhomboid Prisms
Rhomboid prisms have two main application.
1. They are commonly used to displace a laser beam without changing its direction.
2. In imaging applications, they will displace the optical axis without inverting the image.
Rhomboid Prisms ahve two Features
1 Lateral Displacement of Beam
2. Displaces Optical Axis Without Inverting Image

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.
Achromatic Lenses (Doublets) VIS 0° and VIS-NIR coated achromats are also available Correct for on-axis spherical and chromatic aberrations Custom Achromatic Lenses Available
Alpha-BBO Crystals is high temperature phase of BaB2O4 is an excellent birefringent crystal; it is characterized by large birefringent coefficient and wide transmission window from 189nm to 3500nm.
Plano-Concave Lenses have a negative focal length and is typically used to cause a collimated beam to diverge as in a Galilean type beam expander or Telescope. 1. Beam expansion 2. Light projection 3. Expanding an optical system’s focal length
