Crystal wavelength plate for high output laser high output laser
NIHON DEMPA KOGYO CO., LTD.
About This Product
■ Applications
・ Semiconductor exposure device
・ High output laser, etc.
■ Features
・ The highest-purity artificial crystal “N-Grade EX” with excellent laser resistance is available.
・ By using the highest purity artificial crystal "N-Grade EX", it maintains a high permeability even at the absorbent end of the vacuum ultraviolet area due to high laser resistance.
・ It has a high transmittance in the terahertz band and can be used for medical and security use.
・ Large format can be supported up to up to φ200mm (Laser grade).
■ Laser direct joining technology
In order to prevent deterioration of adhesive due to laser, an optical contact -type wavelength plate that does not use adhesive is also available for adhesive wavelength plates. The number of coats can be reduced for the conventional air gap type, and the laser resistance is improved.
■ Product lineup
・ It can be used for round plates and square plates.
・ Polish and sand surface are also available.
・ Correspondence with coat is also possible. Please present the specifications.
