Laser Clean-up Filters

Laser clean-up filters provide up to 90% peak transmission with a centre-wavelength tolerance of 0.5 nm. Mainly used in laser ranging, fluorescence analysis and other spectroscopic applications. Stocked at 405, 532, 633 and 785 nm in three sizes.

Application context

Why this design is used

Application fit depends on the ordered configuration; catalog values are separated from fields that still require confirmation.

Laser beam conditioning

Laser Clean-up Filters: Substrate, coating band and surface figure set the transmitted or reflected wavefront, and the damage threshold sets the power the optic can carry.

Spectroscopy and fluorescence

Laser Clean-up Filters: Edge steepness, blocking depth and passband transmission at the working angle decide how well the excitation is separated from the signal.

Engineering reference

Specify Laser Clean-up Filters from the interfaces inward

Laser Clean-up Filters is a configurable free-space optical component in the Optics, filters and coatings family. The final part number should be released only after the optical, mechanical, electrical and environmental fields below are matched to the intended instrument.

A free-space optic is specified by the wavelength band and angle of incidence its coating is designed for, the clear aperture the beam actually uses, and the substrate, surface quality and damage threshold the application demands. Catalogue figures are quoted at a reference wavelength and angle; performance shifts away from them.

Selection guidance describes the engineering fields that must be checked. It does not assign an option-dependent value that is absent from the catalog record.

Configuration fields to confirm

Wavelength and coating band
State the operating wavelength or band and whether anti-reflection, high-reflection, edge or notch behaviour is required there.
Angle of incidence and polarization
Confirm the working angle and input polarization; coating bands and splitting ratios move with both.
Size and clear aperture
Size the optic from the beam diameter at that plane, including the margin the mount consumes, and state diameter, thickness and tolerances.
Substrate and surface quality
Choose substrate material, surface quality, flatness or figure and centration against the wavefront error the system allows.
Power handling
Provide average and peak power, beam diameter and pulse duration so the damage-threshold margin can be checked.
Mounting and environment
Confirm mount type, orientation, temperature, humidity and cleaning constraints of the coating.

Qualification sequence

  1. 1Define the measurement objective and the performance limit that Laser Clean-up Filters must satisfy.
  2. 2Freeze wavelength, mechanical, fiber and electrical interfaces before selecting option codes.
  3. 3Check loss, noise, heat, motion or vibration contributions in the complete system budget.
  4. 4Confirm the final drawing, pinout, environmental suffix and acceptance test with the quotation.

Technical FAQ

Configuration questions for Laser Clean-up Filters

What must be specified before ordering Laser Clean-up Filters?

Confirm wavelength and coating band, angle of incidence and polarization, size and clear aperture, substrate and surface quality, power handling, and mounting and environment. These fields are coupled, so the final part number should be checked against the complete instrument rather than selected from the model name alone.

How should Laser Clean-up Filters be integrated into the system?

A free-space optic is specified by the wavelength band and angle of incidence its coating is designed for, the clear aperture the beam actually uses, and the substrate, surface quality and damage threshold the application demands. Catalogue figures are quoted at a reference wavelength and angle; performance shifts away from them. Freeze the optical, mechanical and electrical interfaces before releasing the surrounding assembly.

Which documentation should be approved for Laser Clean-up Filters?

Approve the configuration-specific specification, mechanical drawing, connector or pinout definition, environmental suffix and acceptance-test limits supplied with the quotation. Any field absent from the local record remains a confirmation item, not an assumed capability.
