  • Laser Lenses
    Laser beam collimation Lens

    Laser Lenses are used to focus collimated light from laser beams in a variety of laser applications. Laser Lenses include a range of lens types including PCX Lenses, Cylinder Lenses, or Laser Generator Lenses. Laser Lenseare designed to focus light in several different ways depending on the lens type, such as focusing down to a point,  a line, or a ring. Many different lens types are available in a range of wavelengths.

  • IR Optics material
    Infrared Optics Material
    1.  Germanium (Ge) Germanium (Ge) is the preferred lens and window material for high performance infrared imaging systems in the 8–12 μm wavelength band. Its high refractive index makes Ge ideal for low power imaging systems because of minimum surface curvature. Chromatic aberration is small, often eliminating the need for correction.   Crystallographic properties Syngony Cubic Crystal Form Poly or Single Crystal Lattice Constant 5.66 Cleavability <111>, non-perfect Molecular Weight 72.6 Physical properties Density, at 20 °C 5.33 Hardness, Mohs 6.3 Dielectric Constant for 9.37 × 109 Hz at 300 K 16.6 Melting 937 Thermal Conductivity, W/m·K at at 293 K 59 Thermal Expansion, 1/K at 298 K 6.1 × 10-6 Specific Heat Capacity, J/(kgK) at 273-373 K 0.074 Bandgap, eV 0.67 Knoop Hardness, kg/mm2 800 Youngs Modulus, Gpa 102.66 Shear Modulus, GPa 67.04 Bulk Modulus, GPa 77.86 Debye Temperature, K 370 Poissons Ratio 0.278 Elastic Coefficient C11=129, C12=48.3, C44=67.1 Apparent Elastic Limit 89.6 MPa (13000psi) Chemical properties Solubility in water None Solubility in acids Soluble Molecular Weight 72.59 2. Silicon (Si)  Silicon (Si) is grown by Czochralski pulling techniques (CZ) and contains some oxygen that causes an absorption band at 9 microns.To avoid this, material can be prepared by a Float-Zone (FZ) process. Optical silicon is generally lightly doped (5 to 40 ohm cm) for best transmission above 10 microns, and doping is usually boron (P-type) and phosphorus (N-type). After doping silicon has a further pass band: 30 to 100 microns which is effective only in very high resistivity uncompensated material.   CZ Silicon is commonly used as substrate material for infrared reflectors and windows in the 1.5-8 micron region. The strong absorption band at 9 microns makes it unsuitable for CO2 laser transmission applications, but it is frequently used for laser mirrors because of its high thermal conductivity and low density. Application as window, lens in the 1.5 - 8 um region; Mirror for CO2 laser and spectrometer applications.   Crystallographic properties Syngony Cubic Lattice Constant, A 5.43 Physical properties Density 2.33g/cm3 Hardness, Mohs 7 Dielectric Constant for 9.37 x 109 Hz 13 Melting point, оС 1414 Thermal Conductivity, W/m·K at 313 K 163 Thermal Expansion, 1/K at 293 K 2.6x10-6 Specific Heat Capacity, J/(kg°C) 712.8 Bandgap, eV 1.1 Knoop Hardness, kg/mm2 1100 Youngs Modulus, Gpa 130.91 Shear Modulus, GPan 79.92 Bulk Modulus, GPa 101.97 Debye Temperature, K 640 Poissons Ratio 0.28 Chemical properties Solubility in water None Molecular Weight 28.09 3、ZnS material: ZnS MultiSpectral Under intense heat and pressure, defects within the crystalline lattice are virtually eliminated, leaving a water-clear material with minimal scatter and high transmission characteristics from 0.4 to 12 microns. This material is particularly well suited for high-performance common aperture systems that must perform across a broad wavelength spectrum. Specifications: Material: ZnS MultiSpectral Diameter Tolerance: --------------------- +0.0, -0.1mm Thickness Tolerance: -------------------- ±0.1mm Clear Aperture: ---------------------------->85% Parallelism: -----------------------------------3 arc minute Surface Quality: ----------------------------80-50 scratch and dig Wavefront Distortion: -------------------- λ /2 per 25mm @633mm Bevel: -----------------------------------------Protective  (<0.2mm x 45° ) Coating: -------------------------------------- Optional (Uncoated, AR Coating, etc.) 4. ZnSe material ZnSe is a preferred material for lenses, windows, output couplers and beam expanders for its low absorptivity at infrared wavelengths and its visible transmission. For high-power applications, it’s critical that the material bulk absorption and internal defect structure be carefully controlled, that minimum-damage polishing technology be employed, and the highest quality optical thin-film coatings are used. The material absorption is verified by CO2 laser vacuum calorimetry. Our quality assurance department provides testing and specific optics certification on request. ZnSe is non-hygroscopic and chemically stable, unless treated with strong acids. It’s safe to use in most industrial field, and laboratory environments.
