Request InfoDelta Optical Thin Film A/SDelta Optical Thin Film A/S has announced custom linear variable bandpass filters for midsize and full-frame CCD and CMOS sensors. The filters offer high transmission and are fully blocked in the light-sensitive wavelength range of silicon-based detectors. They allow the design of compact, robust and affordable hyperspectral imaging detectors that offer several benefits including higher aperture and transmission than gratings and prisms, short measurement time, high suppression of stray light, and an excellent signal-to-noise ratio. Applications include cancer detection, precision...See full productRelated content from Photonics MediaPRODUCTSPromoted Content August 2022 IssueNew Filters Enable Compact, Lower Cost FluorometerDelta Optical Thin Film has introduced new advanced excitation and emission bandpass optical filters for fluorescence spectroscopy/microscopy that enable more compact and lower cost fluorometers to...Photonics.com 9/6/2022Tilt Compensation PlatformThe Tilt Frame from UpNano GmbH is a tilt compensation platform for the two-photon polymerization (2PP) 3D printing of substrates.

Transmissives include lenses, filters, windows, optical flats, prisms, polarizers, beamsplitters, wave plates, and fiber optics; reflectives include mirrors and retroreflectors. The performance of all may be enhanced with certain substrates and thin film coatings.Lenses come in a variety of shapes, sizes and materials. They can be made of a single piece of glass or have multiple elements; their surfaces can be spherical, aspheric or cylindrical; they can be...Photonics HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery, and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors), and fold light (prisms). While most optical manufacturers make spherical and flat optics, a...Photonics HandbookThin-Film Coatings: A Buyers' Guide: The vast majority of optics used in precision scientific, industrial, biomedical, and military applications incorporate thin-film coatings on their surfaces. Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...WHITEPAPERSPhotonics.com 12/2/2022Innovating the Tunable Light Source - How the Tunable Laser System is Applied in Fluorescence MicroscopyThe market for the tunable light source is ever expanding due to its uses in countless fields, such as the inspection industry, machine visioning, and a wide range of optical experiments....Photonics.com 10/4/2022Product Development Strategies for Electro-Optical SystemsThis whitepaper looks at the unique challenges associated with optical systems by exploring two extremes, an ultra-high precision instrument, and a low-cost consumer product, and the different...Photonics.com 3/16/2022From Hyperspectral Data to a Working End-user Application in the IndustryThis white paper covers the past challenges of using hyperspectral imaging in industrial, machine vision applications.
