Diamond Optics General characteristics of diamond Diamond has some of the most extreme physical properties of any material and is the best semiconductor material ever known. Such properties as its radiation and corrosion resistance, large bandgap, high electron and hole mobility make it an attractive semiconductor for ionizing radiation detectors. Diamond is chemically inert and has highest thermal conductivity (5 times higher than copper). Diamond has the highest radiation-damage level among radiation-detector semiconductor materials. Low carbon nucleus charge, Z=6, provides tissue equivalence of diamond detectors. Type IIa diamond is transparent over an extremely wide spectral range. Applications Windows: High Vacuum Windows RF Power Windows CO2 Laser Exit Windows Attenuated Total Reflection (ATR) Element Process Control Windows Infra Red Windows Detectors: UV X-ray Gamma Neutron Particle Accelerators Non Optical:   Cleavers Surgical blades Anvils Diamond Classification Diamonds are classified depending on the amount of nitrogen contained within material and whether it is held as an interstitial or substitutional defect. type Ia Nitrogen present up to levels of 4000¸ 4500 ppm (0.3 wt %), incorporated in interstitial sites or aggregates. type Ib 500 ppm of nitrogen (0.06 wt %). Incorporated as substitutional point defects. Most of synthetic diamonds are of this type. type IIa Effectively free of nitrogen impurity. Very rare in nature, these diamonds have enhanced optical and thermal properties. type IIb Extremely rare in nature; p-type semiconductor due to boron defects. UralAlmazInvest (UAI) is focused on development and small-batch production of components and devices based on IIa-type natural (ND) high-quality diamonds. UAI offers high-technological diamond-based industrial and scientific products, including plates and windows with wide spectrum of parameters, as well as advanced optical and electronic diamond devices for the following applications: Certified diamond substrates and plates for industrial and science applications with unique thermo, mechanical, optical, electric and radiation resistance parameters; Wide choice of certified diamond windows and optical plates with wavelength range from 0.2 up to 100 microns; Heat-spreaders and heat-conducting substrates with thermal conductivity up to 22W/cm x°C for high-power microwave devices and laser diodes, MCM for integrated circuits, etc. Properties (click here for detailed properties pdf) Lattice constant (Е) 3.567 Density (g/cm3) 3.52 Thermal conductivity (W/cm·K) 20 ¸ 25 Dielectric constant 5.68 Emission wavelength, µm 0.23 Refractive index 2.41 Bandgap (eV) 5.47 Mobility (cm2/V·s)       Electrons 2500     Holes 2100 Saturation velocity (107 cm/s) 2.7 Breakdown field (107 V/cm) 2 Radiation resistance very stable Heat resistance (°C) >1000 Hardness (Knoop), (GPa) 80 Energy to create e/h pair, (eV) 13.6 Diamond Optical Components UAI offers double or single-side polished, plane-parallel discs made of specially selected IIa-type diamonds.
