The passive cooled sensor of the STCam is constructed without cover glass to avoid interference patterns. For sensor protection a low distortion neutral density filter is integrated.
High Resolution CCD Beam Profiler
Instant Beam Propagation & Wavefront Analysis
One Shot M2 Measurement
The BeamWave sensors deliver intensity and wavefront measurements simultaneously in an all-in-one device. Instead of using microlens array for wavefront sampling, these sensors are based on Digital Wavefront Technology ®, hence the number of wavefront measurement points is only limited by camera resolution providing a high spatial resolution wavefront, These sensors are typically used for either simultaneous laser beam profiling and beam propagation analysis or high resolution wavefront measurement for optical elements characterization.
With no moving parts or additional accessories, BeamWave® performs all critical laser beam measurements including intensity distribution, wavefront and beam propagation parameters.

Our CCD is developed to provide excellent sensitivity from the VIS to NIR spectral range. Thanks to its high resolution and its small pixel size, the STCam is a high performance tool for laser beam analysis of continuous wave (CW) and pulsed laser modes. Due to its high dynamic range the STCam captures even higher laser modes with outstanding detail.
The passive cooled sensor of the STCam is constructed without cover glass to avoid interference patterns. For sensor protection a low distortion neutral density filter is integrated. The STCam supports the ultra-fast FireWire IEEE 1394b interface with data transfer rates up to 800 Mbit/s. The plug and play
design facilitates easy and flexible integration and operation.
The portable STCam is designed to be used in a variety of applications in industry, science, research and development, including:
The enhancement of product quality, process reliability and efficiency are just a few of the many benefits of our unique beam profiler cameras. The STCam includes the specifically designed analysis software, STRayCi, which supports Windows XP/Vista operating systems. Its sophisticated software architecture opens up new opportunities in laser beam analysis according to ISO standards.
The concept of the STCam enables easy adaption to standard optical imaging systems, attenuators and opto-mechanical components ensuring highest flexibility. This includes:
Neutral Density Filter:To expand the power range of the STCam several absorptive and metallic-coated neutral density filters are available, which are specified by optical densities ranging from OD 1.0 to OD 4.0.
FireWire Component:We offer different FireWire PCI / PCI Express cards for installation direct into the PC. Standard FireWire cables are suitable for industrial applications and are available in various lengths.
Trigger Device:To synchronize the STCam with pulsed laser systems, our trigger device is perfectly suited. This frequency and delay generator is software controllable and enables the synchronization of up to four beam profilers with different delay times simultaneously.

Our neutral density filters allow broadband attenuation for a spectral range from VIS to NIR. Due to their excellent surface quality the absorptive and reflective filters enable precise beam attenuation for low power applications. The level of attenuation is specified by the optical density. Filters with different optical densities can be combined. A filter adapter is available to mount the filters on the STCam aperture.

Beam Profilers are devices that allow the whole optical intensity profile measurement of a laser beam. They retrieve not only the beam diameter and position, but also the full shape of the beam.
We provide two types of beam profilers: BeamPro with large sensors to measure collimated beams and BeamPro with small pixels to measure focused beams.
We take advantage of our user-friendly software, and provides thorough analysis and statistics of your laser beam. The BeamPro software uses standard communication protocols. It is therefore easily integrable in most complex environments. Several BeamPro can be controlled from a remote screen through the network. They are suitable for wavelengths from 190 to 1100 nm and beams as large as 25 mm. There are also high resolution models with pixels as small as 1.67 μm for focused beam measurements.
