Custom OEM Precision Endoscope Lens Micro Diameter Tight Tolerance Rod
This custom OEM precision endoscope lens program covers micro diameter rod lenses from 0.5mm to 10mm with tight tolerances down to ±0.005mm, providing device engineers with the dimensional control required for miniature endoscope and borescope assemblies. Rather than adapting a catalog part to your housing, we grind each endoscope lens to your drawing, controlling diameter, length, edge break, and end face geometry as a single integrated process. The result is a custom endoscope lens that integrates seamlessly into your assembly with predictable centration and consistent image quality.
Our optical workshop has produced custom rod lenses for medical endoscope OEMs, industrial borescope brands, and veterinary imaging devices for over ten years. The engineering team reviews each drawing for manufacturability, recommends substrate options including BK7, fused silica, or medical grade PMMA, and provides a dimensional inspection report with every shipment. Prototypes are typically delivered within 10 working days, and production tooling is retained so repeat orders maintain dimensional consistency. Whether you need a 1mm micro rod lens for a needle scope or a 6mm relay rod for a rigid arthroscope, this custom OEM endoscope lens service is built around your specifications.

The custom OEM endoscope lens program is built around a documented design review process. Once your drawing is received, the engineering team confirms material grade, coating specification, and inspection criteria before any glass is cut. This up-front alignment eliminates costly surprises that can occur when a micro rod lens arrives with incorrect edge break or incompatible coating. For programs that later move to high volume, the same process files are reused so the custom endoscope lens scales from prototype to mass production without requalification. Customers also receive technical support during assembly, including centration guidance and recommended handling procedures for micro diameter optics.
Product Q&A
Q: What is the smallest endoscope lens you can produce?
We routinely produce micro rod lenses down to 0.5mm diameter with a length of 3mm or more. For diameters below 0.8mm, we recommend fused silica or sapphire substrates because their hardness and stability improve edge yield during grinding and polishing.
Q: What tolerance can you hold on the rod diameter?
Standard production holds ±0.005mm on diameter. For critical centration applications we can tighten this to ±0.003mm with 100 percent dimensional inspection using laser micrometers and air gauges.
Q: Do you keep tooling for repeat orders?
Yes. Every custom endoscope lens project is assigned a dedicated tooling set that is stored and maintained after the first production run. Repeat orders use the same tooling and process parameters, so dimensions and surface quality remain consistent order after order.
Q: Can you help with material selection for our application?
Absolutely. If your device requires sterilization resistance we recommend fused silica; for cost-sensitive consumer borescopes PMMA is an option; for scratch resistance at the distal tip sapphire is the best choice. Share your operating environment and our engineers will specify the substrate and coating.
