CCD Camera

A custom CCD camera capable of operating at 100 million frames per second is available from KAMAN Electro-Optics Dev. Center (Tucson, AZ). The camera’s 10-nsec exposures offer speed-of-light image capture outside the gated-ICCD realm. The units are available as 64 × 64 format with 16-frame burst capability. Individual frame integration is programmable from 10-nsec to 1 μsec within each burst, which can repeat at 400 Hz. Output is 12-bit Camera Link format. The CCD camera is suitable for applications in 3D image capture with a single laser pulse, projectile measurement, and fluorescence studies.

UV Hazard Meter

The X1-1 + XD-9506-4 UV hazard meter and detector from Gigahertz- Optik (Newburyport, MA) can operate and display separate UV-C/B and UV-A detector measurements, and can calculate and display the sum of the two detector readings for UV hazard assessment. The XD-9506 detector covers the ACGIH/ICNIRP UV spectral guidelines by employing two sensor/filter/diffuser combinations, providing separate ACGIH UV-A and ACGIH UVC/B spectral responses. The two-sensor method enables assessment of hazard because the ACGIH/ICNIRP UV-C/B function exhibits approximately 10,000× higher weighting than UV-A.

Imaging Camera

PerkinElmer Optoelectronics (Fremont, CA) has introduced the MultiBlue™ multi-purpose CCD imaging camera featuring 12-bit output depth and USB 2.0 and IEEE-1394b FireWire interfaces that provide dual plug-and-play connectivity. The camera is Windows XP-compatible, and includes an Eastman Kodak KAI-0340SM imager with a pixel resolution of 640 × 480. Other imagers also are available. Using a temperature-stabilized design, the camera eliminates the need for cooling. It is suitable for use in industrial applications such as semiconductor and pharmaceutical inspection.

Laser Event Recorder

OPTRA (Topsfield, MA) offers a laser event recorder that measures, characterizes, and documents laser exposures in support of dosimetry requirements for the protection of personnel working with, or who could potentially be exposed to, laser illumination. The laser event recorder is battery powered and operates for six hours against continuous and pulsed laser sources in the visible and near-infrared portion of the spectrum. The recorder detects laser energy, extracts exposure information such as irradiance level, wavelength, pulse duration, pulse repetition frequency, time and location of exposure, and captures an image of the scene containing the laser. Irradiance levels are compared to the appropriate ANSI standard to determine if the exposure level poses a hazard to eye safety.

Crystal Rotation Stage

Cleveland Crystals (Highland Heights, OH) has introduced the CRS150 counter rotation stage that can facilitate simultaneous angle-tuning of two crystals oriented for compensation of birefringent walkoff. The walkoff compensation configuration provides nonlinear optical conversion, reduces distortion, and minimizes beam displacement. Mounted in a compact footprint, the CRS150 provides operation via computer control with phase-matching software for second harmonic generation or optical parametric oscillation with specific crystals, manual micrometer adjustment, or standalone remote control of a motorized micrometer encoded for readout of relative position.

Document Camera

The TT-02 from ELMO USA Corp. (Plainview, NY) is an XGA-output Visual Presenter that enables users to share information, documents, and small 3D objects with audiences. The camera contains a 5.3× optical zoom, 8× digital zoom, and one-touch auto focus. It features an 850,000-pixel scan CCD for reproduction of full-size A3 documents and 3D objects. At a speed of 20 fps, it captures and displays objects in real time. Its arm design allows the camera to be moved up and down to offer point-of-view images. A switch-selectable output provides an RGB digital signal that goes to a DLP or LCD projector. The signal can be output to NTSC to connect a TV or VCR for viewing and recording. The TT-02 also can be used as a switching device to loop through a PC’s output, allowing the user to switch between the shooting area and a PC display such as a PowerPoint® presentation.

Optical Flats

Optical Surfaces (Surrey, UK) offers standard and custom optical flats measuring up to 600 mm in diameter and manufactured of materials such as glass, Zerodur, and silica. The optical flats can be used for measuring surface flatness of polished areas by determining the variations between work surfaces and the surface of the optical flat. They are suitable for applications in astronomy, laser beam steering, inspecting gauge blocks for wear and accuracy, and interferometric flatness testing of prisms, filters, and optical windows. Surface accuracy of up to lambda/20 p.v. can be achieved, as well as surface roughness of 10 A rms on individual flats. Optics up to 450 mm in diameter are provided with a Fizeau interferometric test report; larger flats are quality assured using the Ritchey-Common test procedure.
