Infrared Zinc Selenide Lenses, windows is for High-Power CO2 Lasers Primary candidate for high-power CO2 Lasers windows For windows, domes and lenses for full infrared region devices, especially for high resolution FLIR systems 1. Broadband AR Coating for the 7 - 12 μm Range 2.  Compatible with Visible Alignment Lasers

Polarizing Beamsplitter Cubes are constructed by cemented two right angle prisms High Damage Threshold Coated for Laser line 355, 405, 532, 633, 780 - 808, 1064 nm or Broadband

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.

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).It's a negative uniaxial crystal and mostly used as visible and near IR polarizers. It has high birefringence, wide spectral transmission and availability in reasonably sized rhombs.

Germanium Windows are applied for IR Wavelength 1. 3 - 5μm for mid-infrared applications 2. 3 - 12μm for broadband multispectral applications 3. 8 - 12μm for thermal imaging applications

Plano-Convex Lenses is best used where one conjugate point (object distance S or image distance S' ) is more than five times the other. This lens shape is near best-form for either focusing collimated light or for collimating a point source.
