Wavelength Budgeting For Optical Filters
Considerations when specifying transition pass bands, blocking bands, and transition widths include filter manufacturing tolerances, thermal tolerances and source/detector variations among others. These factors must be taken into account properly and completely in order to achieve the spectral performance required for an application.  Continue Reading..

Aerial Hyperspectral Imaging: OCI Hyperspectral Imagers
BaySpec’s OCI-UAV hyperspectral imagers are designed for use on small UAVs to monitor the details of spatial, temporal, and spectral representation of ground objects. This app note discusses benefits of these imagers offer and delivers example images for multiple topography analysis.  Continue Reading..
Using 1064 nm Dispersive Raman For Ink And Paint Classification
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.  Continue Reading..

SPECTROSCOPY PRODUCTS

Opto Diode presents a new, two-stage, cooled, lead selenide (PbSe) detector that operates in the mid-infrared (IR) spectral region with peak sensitivity between 4.3 and 4.5µm. The cooler on the BXT2S-28T allows the detector element to operate as low as -45 °C to maximize detectivity (D*).

The IR Detectors (B Series) from Opto Diode are high-performance lead selenide (PbSe) single-channel, cooled, and uncooled devices. Applications for these detectors include gas analysis, emissions monitoring, spectroscopy, thermal imaging, defense, security, and process control systems. 

G&H offers a range of distributed feedback lasers (DFB) that provide smooth, tunable wavelength control and the narrow spectral width required for precise fiber optics. Applications for these products include spectroscopy and fiber optic communications.

BaySpec introduces Breeze-L™, the world’s smartest palm-held spectrometer in the Short-Wave Infrared (SWIR), with the longest wavelength coverage up to 2500 nm. Featuring proprietary miniaturized optics, the Breeze-L™ with its extended wavelength range of 1350-2500 nm, is highly efficient for maximum sensitivity with ultrafast acquisitions. For the first time, a smart spectrometer delivers close to laboratory performance in a palm-held form.

Zygo’s Nexview™ LS650 is a large format metrology system designed as an inspection tool for automated measurement of injection molding tooling, PCBs, glass panels, and other samples requiring an extended work volume up to 650 x 650 mm. It provides 2D and 3D measurements of a variety of surface features with sub-nanometer vertical precision and sub-micron lateral precision.

Need to integrate laser beam measurements in a system? Gentec-EO can make it happen thanks to a broad range of custom solutions. All products can be customized to meet specific requirements and they can all be used as original equipment manufacturing.

Sensors Unlimited’s 1024-LDH2 is a high-speed 1024-pixel, line scan, InGaAs camera that increases the A-line rate to 91,911 lines per second to enable spectral domain OCT to capture detailed 3-D volumes of the retina, nerve head, and choroid layer in the blink of an eye. For 1.31 μm SD-OCT, diode array-based OCT systems offer superior phase stability for doppler or polarization-sensitive OCT.

PCO introduces the new pco.dicam C4 as a fully integrated 4-channel intensified camera system to exploit the full performance inherent to scientific CMOS sensor technology. The pco.dicam C4 distributes the incident light from a single optical input to multiple modules. These modules are capable of detecting very few photons with nanosecond time resolution.

SPECTROSCOPY VIDEOS

  • Hyperspectral imaging technology has advanced significantly in the last 50 years, and Greg Staples with Bayspec talked with us for a few minutes at the 2016 SPIE DCS exhibition about how it has changed.

  • This year at Photonics West, Jason Palidwar with Iridian Spectral Technologies gave us insight into the three optical filtering solutions his company is focusing on in 2016.

  • Si-Ware Systems drew a lot of positive attention at Photonics West 2015 with their Prism award winning MEMS spectral sensors. Bassam Saadany and Mostafa Medhat met with Photonics Online on the last day of the show so we could get a glimpse of the sensors in person and see them in action. If you’re looking to replace your standard bench top FT-IR spectrometer with something much smaller and much less expensive, then this video is most certainly for you.

  • PD-LD's LS-2 LabSource is a dual-source benchtop module features two laser sources, rendering it unique relative to other benchtop Raman modules. These laser sources are VBG-stabilized, and are available in standard and custom wavelengths.

  • Watch this video from Avantes for news on a recent redesign of their tungsten-halogen light source, some beam splitter combiner accessories, and the latest addition to their line of high-sensitivity spectrometers.
