Fluorescence Imaging Filter Sets

Semrock (Rochester, NY) has released four new optical filter sets for fluorescence imaging which enable the choice of substantially increased brightness or enhanced contrast when imaging the fluorescent labels fluorescein (FITC) and green fluorescent protein (GFP). These new BrightLine® filter sets allow the user to either minimize photo-bleaching while increasing image contrast, or receive a light boost for a noticeably brighter image, particularly in low-concentration applications such as single-molecule imaging. The single-band filter sets GFP-1828-A and FITC-2024-A offer the highest contrast of filter sets available today, while the GFP-4050-A and FITC-5050-A sets give the user the highest brightness among sets optimized for these fluorophores.

30-Die, Near-Infrared LED Array

Opto Diode Corporation (Newbury Park, CA) has developed the first in a series of high power LED arrays, the OD-850-30-030. The new 30- die near-infrared (NIR) LED array delivers more efficient operation and higher power with a narrow beam angle of 30 degrees. The device has a peak wavelength of 850nm (min. 840nm and max. 865nm) and a total optical power output of 16 watts. Thermal parameters for storage range from -40°C to 125°C, with the operating temperature range from -20°C to 100°C. The maximum junction temperature is 125°C with a thermal resistance, junction to case, of 0.8°C per watt. Photonics West Booth #5325

Time Delay Integration Cameras

The C10000-601 and C10000-701 series TDI (time delay integration) cameras from Hamamatsu (Bridgewater, NJ) feature back-thinned CCD image sensors with 4096 horizontal pixels and 128 TDI stages (vertical pixels). Each pixel is 12 × 12 μm. Due to their back-thinned structure, the TDI-CCDs feature high sensitivity from 200nm to 1100nm with approximately 90% quantum efficiency in the 600-700nm region. The sensors also feature multiple output ports (taps) to enable high-speed line rates for high-speed imaging. There are three cameras available. The C10000-601 features 8 taps, 50 kHz maximum line rate, 800:1 dynamic range, and an 8-bit/12-bit selectable A/D converter. The C10000-701A has 16 taps, 100 kHz maximum line rate, 256:1 dynamic range, and an 8-bit A/D converter. The C10000-701B camera features 16 taps, 100 kHz maximum line rate, 800:1 dynamic range, and a 12-bit A/D converter. Photonics West Booth #1313

Ultra-Low-Light Color Cameras

FLIR Systems (Wilsonville, OR) has launched its ChromaNox line of EMCCD low light security cameras. Incorporating advanced EMCCD (electron multiplied CCD) technology, the ChromaNox cameras are available in VGA (640 × 480) and SXGA (1280 × 1024) resolution, and in color and monochrome models. The cameras feature proprietary image processing algorithms to bring out hidden image details in difficult scene conditions. ChromaNox cameras meet Mil-Spec operating temperature requirements of -40°C to 71°C. A wide range of ½-inch format C-mount lenses enable both close situational awareness and long-range observation in light levels not considered possible with standard CCD and CMOS cameras. The ChromaNox 6 (640 × 480 resolutions) features analog video and Camera Link® digital video, while the ChromaNox 12 (1280 × 1024 resolution) features a Camera Link digital video output.

Spectroscopy Software Module

A new add-on module for Ocean Optics’ (Dunedin, FL) SpectraSuite Spectrometer Operating Software allows users of the company’s miniature spectrometers and Jaz optical sensing systems to calculate Photosynthetically Active Radiation (PAR), an important parameter for evaluating the effect of light on plant growth. SpectraSuite-PAR uses the absolute irradiance spectrum (captured by the spectrometer) of the light incident on plants and other samples and conveniently converts the irradiance values from μW/cm2 (microwatts per square centimeter) to μmol/m2/s (micromoles per square meter per second), the measurement unit more commonly used for PAR analysis.

Laser Beam Analysis Software

Ophir-Spiricon (Logan, UT) announced recently that Beam-Gage®, the company's next generation laser beam analysis software, now supports the XEVA InGaAs NIR Camera for demanding applications. XEVA delivers high sensitivity in the NIR spectrum (900-1700 nm) at room temperatures. A unique, non-uniformity correction algorithm handles two-point correction plus bad pixel correction to improve image accuracy. The camera's high resolution InGaAs array is formatted for 320x256 with 30 μm square pixels. Based on UltraCal™, Ophir-Spiricon's patented baseline correction algorithm, BeamGage provides high accuracy results, guaranteeing the data baseline (zero-point reference) is accurate to 1/8th of a digital count on a pixel-by-pixel basis.
