Endoscope & Fiber Optic Testing

Endoscope and other fiber optic illuminator lighting systems were previously considered difficult to trouble shoot in the field, and were commonly sent out to certified laboratories for evaluation, repair, replacement or service. In many cases expensive components were simply swapped out for new parts when test equipment was too costly or unavailable.

ILT offers a selection of portable light measurement testing systems that allow easy measurement of fiber optic lighting systems including endoscopes, laparoscopes, cystoscopes, microscope illuminators, spot curing sources and more. Along with testing the output of the fiber, ILT light meters can also be configured for measurement of the light source directly.

ILT meters come with NIST traceable, ISO 17025 accredited calibrations in units of Watts, Lumens, Watt/cm2, lux and foot-candles as well as full spectrum analysis.

Input optics, including small cosine receptors, integrating spheres, narrow beam adapters and apertures (for testing uniformity) can be added to ILT systems making them the most versatile systems available.

ILT engineers and technical support staff are available to customize systems to the unique requirements of our customers.

Use the table below to identify the system (meter + detector) that meets your specific application.  Use the table to find the spectral range you wish to measure.  The table can be filtered to show our meters by type, (e.g., hand-held), as well as searching on the minimum and maximum spectral range you wish to measure.  The tables can also be sorted to group systems by meter type, spectral range, measurement range, and units.  Click the product link of the system to view it's details.
