Phase masks

The LPM Series of long phase masks are available in lengths u¥to 100 mm for production of and research on fiber Bragg gratings. The phase masks are made by interfering two laser beams, which allows continuous chir¥over the entire length of the mask rather than the quantized chir¥characteristic of e-beam-written phase masks. The period of each mask can be measured to a precision of ۪.1 nm.
