Ir Optics Silicon For Co2 Laser
Posted at: Offers to Sell and Export | Posted on: Tuesday 21 April 2009 1:53 pm | Poster last visit: Thursday 12 March 2015 |
Product Description:
Introduction: 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. Silicon is also useful as a transmitter in the 20 micron range.
Main Properties： Crystal Class Cubic
Lattice Parameter a=5.43Ĺ
Melting Point 1417℃
Mohs Hardness 7
Transmission Band 1.5-8um
Density 2.329g/cm3
Young’s Modulus 130.91 GPa @40℃
Thermal Conductivity 1.63W/cm/K
Specific Heat 0.18cal/g/K @25℃
Thermal Expansion 2.6x10-6/℃ @20℃
Lasertec supply Si crystal with：
Diameter +0/-0.10mm
Length +/-0.2mm
Chamfer 0.20+/-0.10mm @ 45°
Surface Figure (power/irregularity) at 0.63µm 1.0 fringe/0.5 fringe
Parallelism < 40 arc Seconds
Perpendicularity < 5 arc min
Surface Quality 40/20Scratch/Dig
