BSC100 Optoelectronics Engineering Services Babinet-Soleil Compensator HIGHLIGHTS APPLICATIONS • Broad wavelength range 400-1100 nm • Polarisation measurement • High phase contrast 1/500 λ • R D • Stable construction • Quality control PRINCIPLE OF OPERATION Due to the cement-free construction, the unit may be used at relatively high The BSC100 Babinet-Soleil power densities. compensator comprises one long (44mm x 14mm) and one short wedge (14 x 14mm) of crystalline quartz with identical wedge angles. The thickness of the wedges are adjusted such that a relative optical retardation of zero occurs in the middle of the optic. The optic is housed in a precision linear translation mechanism and ist adjustable via a micrometer screw. APPLICATIONS The BSC100 serves as an adjustable retardation element for all wavelengths within the transmission range
