Diffraction Gratings

Bach Research offers a comprehensive range of ruled master and replica gratings, both plane and curved, for a variety of applications:

For Laboratory Instrumentation – e.g. monochromators and spectrophotometers - where substrates are typically float glass or pyrex glass.
For High Power Lasers – used as both intracavity components and output couplers – where substrates are typically copper, stainless steel or invar.
The master grating list includes line spacings from 6.61 to 3600 lines per mm and blaze wavelengths from 75nm to 77μm.

In addition, Bach offers a competitive custom ruling service when the requirement is not covered by one of their extensive master inventory.

Bach has a particular expertise in the manufacture of Echelle type gratings and in satisfying the demanding requirements of one-of-a-kind optical hardware that has found itself booked on many space missions, from Voyager to the James Webb Space Telescope due to launch in 2018.

Seeing the world through other eyes with The Imaging Source cameras

Cameras from The Imaging Source can be found in many areas of everyday life: industry, food and beverage production, research sciences, pharmaceuticals and medicine, traffic and parking management. Applications in sports, leisure and media are also taking hold. The human eye is limited to a small range of visible light, but the cameras and software from The Imaging Source make the invisible - visible. Machine vision technology and efficiency which improves the quality of life for everyone by protecting lives and making them safer and more enjoyable.
There are in excess of 100models available to cover most applications. 
Products include industrial, microscope, autofocus, zoom and board cameras. A large selection of sensors used include SONY CCD EXview, CMOS Pregius and Starvis, and CMOS Python and Aptina from ON Semiconductor. 
Outputs include GigE Vision, USB2.0, USB3.0, USB3.1 and FireWire.

Bitflow Inc

BitFlow has been developing industrial frame grabbers and software for the imaging industry since 1993. They specialize in interfacing to cameras with very high data/frame rates. Their frame grabbers are utilized in environments with complex triggering and I/O requirements. Typically, by use of their proprietary FlowThru architecture the CPU load is reduced and their frame grabbers are at their best running in applications where every CPU cycle is precious.
BitFlow frame grabber interfaces are Camera Link, CoaXPress, and Differential. Their software is some of the easiest to use, yet incredibly powerful and reliable. They offer APIs to the common image processing software packages and will work with you on your custom software to ensure you are up and running in no time.
New Imaging Technologies - Seeing beyond the visible

New Imaging Technologies (NIT) offers CMOS and InGaAs imaging sensors and cameras operating over an extraordinary dynamic range of more than 140dB. The sensors are particularly useful for machine vision, automobile and autonomous driving, biometrics, security and surveillance. NIT delivers from large volume production down to small numbers and custom products. Their facility is fully ISO9001 accredited.
Their SWIR or Short-Wave InfraRed imaging covers the wavelength range from 900nm to 1700nm. A large number of applications that are difficult or impossible to perform using visible light are made possible, with impressive results, using short-wave infrared (SWIR) imaging, thus enabling the user to "See Beyond the Visible". SWIR is similar to visible light in that photons are reflected or absorbed by an object, providing the strong contrast needed for higher resolution imaging – unlike thermal imaging systems, that rely on radiated photons. 
NIT range of SWIR cameras includes QVGA and VGA models with USB3.0 CameraLink and analog interfaces, in Compact, Smart, Gated and Smart Gated variants.

Tucsen Photonics Dhyana family 

Tucsen is a well-respected manufacturer of high performance microscopy cameras.
Their high-end product range aimed at the ultra-low light applications, from life science (including fluorescence) to astronomy, is the Dhyana family of cooled cameras featuring back-illuminated Scientific CMOS sensors with a super-high Quantum Efficiency, extremely low noise, high dynamic range and wide spectral response. All models offer at least video rate framerates. 
All cameras use USB3 interface. The recently revised software is capable and user friendly. 
The flagship model is the Dhyana 95. Its designation alludes to the fact that its Quantum Efficiency is 95% at 560nm, which a front illuminated sCMOS camera cannot match, and rivalling the best EMCCD cameras. In addition, Dhyana 95 has a spectral response range from 190nm to 1100nm, thus making it very useful in UV, VIS and NIR bands.
Dhyana 95 uses a 2in format (31.9mm diagonal) sensor with 2048x2048 resolution and 11μm square pixels. Maximum framerate is 25fps at full resolution.
Dhyana 400A uses a lower performance version of the same sensor, with QE of 60% at 600nm (monochrome). Maximum framerate is 25fps at full resolution.
Dhyana 400D uses a 1.2in format (18.8mm diagonal) sensor with 2048x2048 resolution and 6.5μm square pixels. Its QE is 65% at 650nm (monochrome). Maximum framerate is 35fps at full resolution.
Dhyana 200A uses a 1in format (15.3mm diagonal) sensor with 2048x1152 resolution and 6.5μm square pixels. Its QE is 65% at 650nm (monochrome). Maximum framerate is 64fps at full resolution.
All Dhyana cameras are also available in colour versions.
