The Skylark NX lasers at 349 and 640 nm deliver reliable, high quality output to support optical grating mastering and fabrication.
Optical grating mastering is a process used to create diffraction gratings on optical surfaces such as crystals, semiconductor materials, and specialiced optical coatings.
The gratings have closely spaced parallel lines or grooves that diffract light in specific ways, enabling applications such as spectroscopy, wavelength dispersion, and laser tuning.
Optical grating mastering typically involves using laser interference or etching techniques to apply diffraction patterns on a substrate.
High power
Enables shorter exposure times to reduce disruptive external influences like vibrations.
Ultra-stable output
Power stability and low noise help avoid fluctuations in output power during the optical grating production process that could cause inaccuracy.
Excellent beam quality
Laser output with a well-defined beam profile, low divergence, and pointing stability makes it easier to precisely focus the light source onto the grating surface.
