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
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.

3. Expanding an optical system’s focal length
Plano-Concave Lenses are with negative focal lengths and they can be used to diverge collimated beams; in this case, the curved surface should face the source in order to minimize spherical aberration. In addition, they can be employed to offset the effects of spherical aberration caused by other lenses in an optical system. Because the spherical aberration of the Plano-Concave is negative, it can be used to balance the aberration of other lenses.
WTS offer N-BK7 Plano-Concave Lenses, Fused silica Plano-Concave Lenses, Calcium Fluoride Plano-Concave Lenses etc.

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.
Fused Silica material Advantages With Good UV and IR transmission, Low thermal expansion, providing stability and resistance to thermal shock, Wider thermal operating range and High laser damage threshold make Fused Silica windows could used for Laser, Medical, imaging etc. application.
30° - 60° - 90° Littrow Prisms have two main applications. 1. Uncoated littrow dipersion prisms are used to disperse light into its component spectrum. 2. Coated littrow dipersion prisms are used to deviate the line of sight by 60°.
