Description
Compensation plates are made of Calcite. Plates are available with different orientation for different Group Velocity Delay compensation – starting from tens of femtosecond up to tens of picosecond delay compensation.
Standard GVD compensation plates are adjusted for required compensation by angular tuning changing the angle of incidence. Suggested AOI is -5 to +5 deg, however they also can operate at larger AOI.
Standard plates are made of 14×14 mm aperture, clear aperture dia 12 mm and mounted in to 1” ring holder. The optical axis is at special orientation – non parallel to faces of plate.
AR coatings for custom wavelengths are also available.
