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

Mirror is an object with a surface that has good specular reflection. that is, it is smooth enough to form an image. The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirror are also used, to produce magnified or demagnified images or focus light or simply distort the reflected image.
WTS make Silver Coated Mirrors, Gold Coated Mirrors, Aluminum Coated Mirrors, Dielectric Coated Mirrors.
The shape could be circle, square, elliptical or right angle prisms or glued together.

Double Convex Lenses, Bi-convex Lenses have two outward curved surfaces, a positive focal length and are useful for 1:1 imaging and in multi-element systems.These lenses are designed to have a focal length of f= (R1*R2)/((n-1)*(R2-R1)) 1. Supported by the Zemax Optical Design Package 2. Posistive Focal Length 3. Material upon requirement
Selective Absorption Colored Glass Filters This part of the glasses can be divided into 14 kinds and 78 types based on the color and application in this catalogue.
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.
Yttrium Vanadate (Nd:YVO4) is one of the most efficient laser host crystal currently existing for diode laser-pumped solid-state lasers.
