Wedge prism is an optical element having plane-inclined surfaces, usually the faces are inclined toward one another at very small angles. Wedges divert light toward their thicker portions. Wedge prism is commonly used in laser system for eliminating the reflections from the second surface or for beam steering. Standard and broadband antireflection coatings are available upon request, see our standard optics components below. We supply optical wedge prism. Specification of our wedge prism as follow: *Material:BK7 or(JGS1 JGS2 JGS3) *Dimension Tolerance:+/-0.20mm to +0.01/-0.01mm *Thickness Tolerance:+/-0.20mm to +/-0.005mm *Surface Quality:80-50 to 10-5 Scratch/Dig *Surface Flatness: at 632.8nm lambda to lambda /20 per 25mm *Clear Aperture:80% -- 100% *Angle Tolerance:3-5 minutes to 3 second *Chamfer:0.3+/-0.20mm *45degree *Coating Optional

Lithium Niobate(LiNbO3) Crystal lens is widely used as frequency doublers for wavelength > 1 mm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices. Due to its large Electro-Optic (E-O) and Acousto-Optic (A-O) coefficients. We manufacture LiNbO3 crystal lens professionally. Basic Properties of optical LiNbO3 crystal lens as follow: Crystal Structure:Trigonal, point group 3m Lattice Parameters:a=b=5.148 , c=13.863 Density:4.64 g/cm3 Melting Point:1250 degrees Curie Point:1142+/- degrees Mohs Hardness:55 Dielectric Constant :e11/e0 = 85; e33/e0 = 29.5 Thermal Conductivity:38 W/m egrees at 25 egrees Thermal Expansion Coefficient:a1=a2 =2x10-6 egrees, a3=2.2x10-6/ degrees at 25degrees Piezoelectric Strain Constant:d22 = 2.04 x 10-11 C/N, d33 = 19.22 x 10-11 C/N Elastic Stiffness Constant:CE11 = 2.04 x 1011 N/m2, CE33 = 2.46 x 1011 N/m2
