Custom OCT Probe Design and Manufacturing

Go!Foton presents the Precision Beam Profile Converters (PBPCs)

PBPCs customize beam waist diameter and beam waist position per customer requirements. They can produce a collimated beam, a focused beam, or a diverged beam.

Go!Foton arranges the production and assembly of a full OCT probe including prism, torque coils, and other components with the PBPC. Go!Foton can provide assembly methods using medical adhesives or ultrasonic welding. Go!Foton also works with subcontractors to characterize and produce high volume specialty prisms for OCT.

The Original Lens For Endoscopes

Go!Foton also brings to market the SELFOC Rod Lens product produced by NSG Group in Japan. The origin of its SELFOC lens dates back to 1968 and the original objective was to develop a lens for fiber-optic gastric endoscope. In the process, the NSG researchers succeeded in producing the world’s first gradient index lens in a glass rod. From there, they developed lenses that could transmit images and light coming from one end of the glass even when both ends were flat. The product name SELFOC comes from “self-focusing.” In this lens, the index of refraction declines rapidly as light moves from the center to the periphery. Today the SELFOC Rod Lens is widely adapted in endoscopy applications.

SELFOC Imaging Lenses

The SELFOC Imaging lens is commonly used as an objective lens for small diameter imaging systems where conventional lenses are not suitable due to size limitation. The lens is designed to gather light from an object and form an inverted image at the back surface of the lens. Typical applications include fiberscope (attached to a coherent fiber bundle) and rigid endoscope (attached to a relay lens such as a SELFOC Rod Lens, see next section).

SELFOC Imaging Lenses are specified somewhat differently that SELFOC Micro Lenses (SML). While SML performance is controlled through the lens pitch and gradient constant (√A), Imaging Lens performance is controlled via the working distance (WD) and image quality factors such as resolution and field curvature. For this reason, ILW and ILH lenses can consistently exhibit good image quality despite variations in √A and/or Z (Lens Length).
