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
Positive meniscus lenses is convex-concave lens thicker at the center than at the edges, which frequently used for beam focusing applications.
Negative meniscus lenses is convex-concave lens thinner at the center than edges, which frequently used for beam expanding applications.

Positive meniscus lenses and Negative meniscus lenses
Positive meniscus lenses is convex-concave lens thicker at the center than at the edges. They are used to minimize spherical aberration. When used in combination with another lens, it’s will shorten the focal length, and increase the NA of system.
1. Frequently Used for Beam Focusing Applications
2. Minimizes the Increase in Spherical Aberrations for Multi-Element Systems
Negative meniscus lenses is convex-concave lens thinner at the center than edges. They increase the divergence of the beam without introducing any significant spherical aberration. When used in combination with another lens, they will increase the focal length, and decrease the NA of the system.
1. Frequently Used for Beam Expanding Applications
2. Minimizes the Increase in Spherical Aberrations for Multi-Element Systems
