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

Pyramid is a three-dimensional figure that, unlike a prism, only has one polygonal base. The vertices of the base are joined by segments creating lateral faces shaped like triangles that meet at one point above the base of the pyramid. That point is called the vertex of the pyramid. You may also see that point called the apex of a pyramid.
WTS could make customized Pyramid prisms with different material, different size.

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
Bandpass filters are allow special wavelength for transmission and block all other wavelength light.
ZnSe is used widely for IR components, windows and lenses, and applied for Thermal Imaging, FLIR, Medical systems and Co2 Laser
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.

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.
