How NDAR Coating Solves Transmittance And Reflectivity Challenges

Colored glass neutral density (ND) filters can suffer from uneven transmittance and fitment issues. Standard coated ND filters can struggle with reflected light. HOYA offers a filtration solution to address these challenges.

Detecting Disguises At Border And Immigration Security Checkpoints Using Short-Wave Infrared (SWIR) Cameras

As the U.S. continues to increase its security at border crossings, airports, and other points of entry, biometrics will play an important role. Fingerprints and other direct contact means will become final identifiers of persons.

High-Pulse Laser Rotary Encoders: Positional Angle Mastery In A Tiny Package

The use of high-pulse optical-digital laser rotary encoders benefits applications where sensing or controlling the rotation and position of a mechanical system with high accuracy and exceptional resolution is required.

The Challenges Of Infrared Radiance Measurement

IR cameras are used on the military test range primarily to measure the radiance of various targets. Understanding how radiance measurements work allows users to decide whether a camera is properly calibrated for their application.

Atomic Force Microscopy Enhances The Nanoscopy Toolkit

Atomic force microscopes are ideal for nanomechanical characterization, bringing utility to nanoscopy applications and excelling in conditions where low light presents challenges or sample integrity is vital.

Finished Infrared Optics

PG&O finished infrared (IR) optics are designed for a range of applications, including biomedical, industrial, military/defense, homeland security, surveillance, and more. These optics operate from 0.75 µm, the near-infrared (NIR), out to 15 µm, the longwave-infrared (LWIR) spectrum.

Using 1064 nm Dispersive Raman For Ink And Paint Classification

 In the past, Raman spectroscopy was not useful for forensics because most "real-world" samples have a vivid color, whose fluorescence could overwhelm Raman signals. This issue is resolved by BaySpec’s1064 nm excitation dispersive Raman systems that offer maximum reduction in fluorescence interference.

IR Detectors: BXT2S-28T Two-Stage Cooled PbSe Packages

Opto Diode Corporation's two-stage, cooled, lead selenide (PbSe) detector operates in the mid-infrared spectral region with peak sensitivity between 4.3 and 4.5 µm. The cooler on the BXT2S-28T allows the detector element to operate as low as -45 °C to maximize detectivity. The device also features responsivity of 7.5 x 104 V/W (typical). The reliable detector provides the highest sensitivity when monitoring small changes in gas mixtures.
