They are used to isolate certain wavelengths or colors. Applications range from detecting the gaseous composition of a distant star to visualizing the chemical activity in a human cell. Ultraviolet (UV) bandpass filters (with effective wavelength ranges below 400 nm) pose unique design and manufacturing challenges related to the absorption of materials at short wavelengths.In their earliest forms, UV bandpass filters that were optimized for wavelengths less than 400 nm, such as the Schott UG or the Hoya U-series, were constructed of absorbing compounds in glass. Such...Photonics HandbookRules of ThumbPhotonics Rules of Thumb Scientists and engineers tend to want to answer simple relational questions with a blackboard covered with equations, even when questioners just want a rough estimate to...Photonics HandbookPlastic Optics: Specifying Injection-Molded Polymer Optics: The versatility of polymer optics opens new doors for optical designers who understand the whys and hows of specifications.The use of precision polymer optics is becoming an increasing necessity today as products demand sophisticated light handling components to achieve desired results.
