Optical equipment

Distinguish decorative black from functional low-reflection needs. Low-reflection selection requires the working wavelength, optical measurement method and surface condition to be specified.

Application needs

Distinguish decorative black from functional low-reflection needs. Low-reflection selection requires the working wavelength, optical measurement method and surface condition to be specified.

Part types open for discussion

Light-shielding structural parts, internal barrel parts and precision supports. This is an application evaluation direction and does not indicate that any specific customer project has been undertaken.

Prepare before evaluation

Working band, reflectance target, substrate roughness, cleanliness and assembly requirements.

From requirement to verification

  1. Submit drawings stating the substrate, quantity and operating conditions.
  2. Engineers check pretreatment, coating system, thickness and assembly requirements.
  3. Arrange sample verification as needed, and confirm quotation and acceptance conditions.
