Do You Know What You Are Really Buying?

In order to help optical designers and engineers view optical datasheets more critically and ask the right questions of lens providers, this article discusses key datasheet parameters such as modular transfer function (MTF), focal length, and f-stop.

Fluorescence Lifetime Imaging — Application Simplified

Photoluminescence is used for a variety of life science applications, including biomarkers, sensing, and fluorescent lifetime imaging. The pco.flim camera system is the first luminescence lifetime imaging camera designed to use a two tap CMOS image sensor. 

Lens Manufacturers: Do You Know The Best Test For Lens Performance?

A high-quality lens begins with a good design, tolerant to small manufacturing errors. The manufacturing process must be tightly controlled, from individual lens elements to final assembly. But, since small errors in manufacturing can result in serious loss of performance, end-of-line testing is necessary.

Enhancing Endoscopy With Optical Filters

Endoscopic examination is a key technique used to diagnose early-stage neoplastic lesions associated with stomach and other gastrointestinal cancers. While white-light reflectance (WLR) imaging has become the standard for in vivo diagnosis using “conventional endoscopy,” this white paper details three alternatives — or supplements — to WLR that leverage the wavelength selectivity provided by optical filters:  narrow-band imaging (NBI), auto-fluorescence imaging (AFI), and endoscopic Raman spectroscopy.
