Since 1968, Scientech has been an industry pioneer in the development and manufacture of award-winning laser power and energy measurement instruments. Scientech provides quality, American-made, precision laser power measurement equipment to laboratory, industrial, academic, medical, government and other unique laser applications worldwide. Our power detectors cover a wide range, from microwatts to megawatts. Choose from our: Radiation Pressure Series Astral Series Calorimeters Vector Series Pyroelectric or Calorimeter Detectors Custom Laser Power Measurement Instruments and Accessories
Scientech offers a wide range of both surface and volume-absorbing calorimeters, with apertures of custom sizes or standard 8mm, 16mm, 25mm, 50mm, 100m and 200mm aperture models.
The Radiation Pressure Series is Scientech’s newest innovation, designed to accurately measure high power levels from lasers that would normally require expensive, large water-cooled calorimeters. These instruments measure the radiation force exerted by the laser beam on a mirror and significantly improve response time, size, and scalability. The mirrors are designed to reflect ≥99.999% of the laser energy and allow continuous measurement. Radiation Pressure Series instruments actually improve in accuracy as laser power increases.
Scientech builds a wide variety of pyroelectric detectors. High damage threshold HD and HDX models can withstand energy densities up to 1.4 J/cm2 and 12.6 J/cm2 respectively. Vector detectors are available in high absorbing, high rep rate, and high damage threshold models, with normal and slim profiles.
Scientech offers a wide selection of accessories for our detectors and power/energy meters to support or enhance your laser measurement. Fiber optic holders and adapters are available to allow direct fiber optic cable attachment to Astral and Vector 25mm calorimeters as well as Vector pyroelectric detectors (except the SP and HR models). Contact us if you have other fiber optic connector needs. For measuring at low power or energy (<30 mW or 30 mJ), Scientech recommends application of our Isoperibol™ enclosure to minimize environmental thermal interference. Isoperibol™ model 360203A is designed for use with 25mm aperture detectors, except slim profile models. Isoperibol™ model 360203F is designed for use with our PN 12420 adapter that attaches fiber holders to our 25mm detectors. A high-speed photodiode designed to attach to 25 mm Astral or Vector calorimeter apertures provides a temporal profile of the laser pulse when viewed on an oscilloscope. A wide variety of detector mounting assemblies are available for mounting the detector to an optical bench. Posts are available in 1/2" and 3/4" diameter and from 2 to 6 inches in length that attach to a selection of mounting bases.
