Catalina Scientific is a software developer, dealer and manufacturer's representative for some of the highest performance CCD cameras used in scientific and industrial applications. Our products include an echelle-type spectrograph system that combines a CCD camera, an innovative cross-dispersing echelle spectrograph and our KestrelSpecTM imaging spectroscopy software. We also supply imaging systems using high-resolution, cooled and uncooled CCD and CMOS cameras for applications in microscopy, biology, astronomy, machine vision and high-speed photography.
Our echelle-type spectrographs produce high resolution over the entire UV-VIS-NIR spectral region in one image, without scanning. Unlike a standard scanning spectrograph, an echelle has no stepper motor and no moving parts. Just one CCD image is required to cover a wide spectral range because the cross-dispersing optics allow the use of multiple orders, instead of just one order like a standard spectrograph.
We have two types of echelle spectrographs, the SE 100/200 and the new EMU-65:
The SE 200 has been widely used in national labs, universities and private industry around the world since 2001. The smaller SE 100 was introduced in 2006.
The high-throughput EMU (Echelle Multiplex Unit) was first developed as a prototype for a future Mars Rover mission for NASA. The F/3 or faster EMU-65 is designed for low-light applications using high resolution and extremely low noise EMCCD cameras. The light throughput of the EMU is an order of magnitude higher than any other echelle spectrograph using the same sized slit.
Our KestrelSpecTM Imaging Spectroscopy software, originally introduced for the Macintosh by Rhea Corporation, has been available for Windows® for 15 years. The software supports imaging spectroscopy applications using CCD cameras combined with commercially available fixed-grating and scanning spectrographs, as well as our echelle spectrographs.
The SE and EMU echelle spectrographs are ideal for applications requiring broad UV/VIS/NIR wavelength coverage at high resolution, such as LIBS (Laser Induced Breakdown Spectroscopy). Our spectrographs have been instrumental in detecting CBRNE (Chemical, Biological, Radiological, Nuclear, Explosives) substances using LIBS techniques. The EMU-65 VIS/NIR instrument, with its broad spectral range and fast F/2 throughput with high resolution, can be used with lasers at multiple wavelengths for both Raman spectroscopy and photoluminescence analysis. Forensic science and environmental studies are two more fields where our spectrographs have played a vital role. With its high throughput and high resolution over a broad wavelength, the EMU-65 is ideal for a compact, portable system for OES/AES (Optical/Atomic Emission Spectroscopy).
Catalina Scientific has been a value added reseller for various CCD camera manufacturers for 15 years. We supply imaging systems ranging from 16-bit dynamic range, cooled, slow-scan CCD cameras to 1K x 1K CMOS cameras that can provide 150 fps (>7,000 fps @ 128 x 128 ROI) with better than 8-bit dynamic range. We can supply either non-intensified or gated intensified cameras or EMCCD cameras depending upon the application.
