Collimated (telecentric) illumination, beam dia. 26-240 mm (LS-VCL-170-XW-Y)

Collimated illuminators designed for telecentric lens imaging; they can directly provide backlight or ortho illumination (spectral devices are required). Parallel illumination makes full use of the telecentric lens and helps improve system accuracy and depth of field.

Features

• Specially designed for telecentric lens imaging
• Backlight directly, or ortho illumination (spectral devices are required)
• Parallel illumination makes full use of the imaging potential of telecentric lenses and greatly improves system accuracy
• Parallel illumination can optimise the depth of field far beyond the nominal value
• Multiple wavelengths, 1W / 3W power selection, built-in brightness adjustment
• Specially designed for telecentric lens imaging; directly realises backlight or ortho illumination (spectral devices are required)
• Parallel illumination makes full use of the imaging potential of the telecentric lens and greatly improves system accuracy
• Parallel illumination optimises the depth of field of the imaging system so that it is far beyond the nominal value
• Multiple wavelengths, 1 W / 3 W power selection and built-in brightness adjustment device
• Specially developed for backlights for objects inspected by telecentric lens
• All light from the VCL series light source collected by the telecentric lens goes into the camera to ensure high SNR
• More accurate imaging compared with diffusing light sources by decreasing diffuse reflection on edges
• Develops telecentricity and DoF for the telecentric lens
• Brightness adjustable (rear ring, per drawings)

Applications

• Telecentric backlight / coaxial (ortho) illumination for telecentric lenses
• Backlight or ortho illumination for telecentric lens imaging and measurement
• Backlighting for telecentric lens measurement
