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

Achromatic Waveplates(Retarders), AWP is composed of one piece of Crystal Quartz and one piece of Magnesium Fluoride, MgF2. Unlike standard waveplates, AWP provide a constant phase shift independent of the wavelength of light that is used. The Retardation tolerance of our AWPs is better than λ/100 over the entire wavelength range.The flat response of an AWP is ideal for use with tunable lasers,multiple laser-line systems and other broad spectrum sources.

High Presion Double Concave Lenses and Bi-concave Lenses
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
LiNbO3 and MgO-LiNbO3 Nonlinear Crystal
LiNbO3 crystal is widely used as frequency doublers for wavelength > 1mm and optical parametric oscillators (OPOs) pumped at 1064 nm.
High Precision Nd:YVO4 Laser Crystal
Yttrium Vanadate (Nd:YVO4) is one of the most efficient laser host crystal currently existing for diode laser-pumped solid-state lasers.
High Accuracy Corner Cube Prism
Retroreflectors (Corner Cube Prisms) reflect an image or beam back toward its original direction via three total internal reflections (TIR) 180° Reflection Inverts Image 3 arcsec Beam Deviation
Optical Coated Bandpass Filters
Bandpass filters are allow special wavelength for transmission and block all other wavelength light.
High Precision Optical Glass Penta Prisms
Penta prisms are five-sided prisms featuring a ray deviation of 90° and a right handed image 90° Deviation of Beam or Image Right Handed Image Coating are avaliable
