Opto-Line uses a proprietary method of fabricating the distal aperture for endoscopes and laparoscopes. The centricity and accuracy are of utmost criticality to our customers and we exceed these requirements.


High Quality Apertures for Medical Endoscopes

The smallest aperture size we’re able to resolve is about 2um. Typical substrates inclue N-BK7, B270, D263, fused silica, and sapphire, but we can use other specified material as well. Typical aperture coating utilizes our proprietary black chrome: Very durable, low reflecting in visible with Rave <5% , OD > 4.0. Pinhole free. Excellent edge acuity and accuracy (± 1um). We can also deposit other required materials such as high reflective protected aluminum, gold, etc.

  • Glass thickness: Minimum we can handle is ~ 0.10 mm thickness
  • Requirements: Most endoscopy aperture customers requires AR coatings on both surfaces. We often utilitize low-scatter BBAR <1% Rave in visible, but we can address our customers’ needs on a project by project basis.
