For over 20 years, Opto-Line has specialized in providing the highest quality apertures for medical endoscopes.   Typically utilizing our proprietary low-reflecting black chrome, our apertures have become the benchmark for endoscope manufacturers.

Pinhole-Aperture

The smallest aperture size we’re able to resolve is about 2um.  Typical substrates inclue N-BK7, B270, D263, fused silica, 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
  • Most  endoscopy aperture customers requires AR coatings on both surfaces. We often utilitize low-scatter BBAR <1% Rave in visible, but we can address each customers’ needs on a project by project basis.

Endoscopy is a nonsurgical procedure used to examine a person’s digestive tract. Using an endoscope, a flexible tube with a light and camera attached to it, your doctor can view pictures of your digestive tract on a color TV monitor.

During an upper endoscopy, an endoscope is easily passed through the mouth and throat and into the esophagus, allowing the doctor to view the esophagus, stomach, and upper part of the small intestine.

Similarly, endoscopes can be passed into the large intestine (colon) through the rectum to examine this area of the intestine. This procedure is called sigmoidoscopy or colonoscopy depending on how far up the colon is examined.

A special form of endoscopy called endoscopic retrograde cholangiopancreaticography, or ERCP, allows pictures of the pancreas, gallbladder, and related structures to be taken.
