Product of the Month: Lenses for Hostile Environments

Marshall’s Industrial and Security Division (El Segundo, CA) has developed a new series of pinhole lenses designed to protect employees when monitoring high temperature and/or hostile environments. The V-ZPL-HITEMP-A and V-ZPL-HITEMP-B zoom pinhole lenses permit reliable monitoring in temperatures up to 1000°. The V-ZPL12 series pinhole lens, available with motorized or manual zoom control, offers a 4-20mm angle of view and can be used for situations when the camera must be hidden from view. The V-PL150C, V-PL200C, and V-PL300C long focal lenses are designed for covert operations and can be used when looking through walls up to 14.81" thick.

Shadowgraph Camera

The Specialised Imaging Shadowgraph (SIS) camera from Specialised Imaging (Tring, UK) enables high resolution digital imaging of ultra-fast events in ambient and low-light environments. Integrating this camera with an ultra-fast, high-intensity spark source results in a sophisticated digital shadowgraph camera that offers instantaneous access to data. Comprehensive triggering functionality enables the SIS camera to be interfaced with a wide range of triggering devices.

High-Power Titanium Sapphire Coatings

Laser Components (Hudson, NH) offers solid state laser coatings with high damage thresholds, including coatings for Q-switched lasers at 1064 nm, 532 nm, 355 nm, or 266 nm. Coatings for short pulse lasers at 800 nm also exhibit excellent damage thresholds. The damage threshold measurement values were determined using a 780 nm Spectra Physics laser, featuring 1 kHz repetition rate and 140 fs pulse length, according to ISO 11254-2.

Highly Aspheric Mirrors and Lenses

Optical Surfaces Ltd (Surrey, UK) can generate highly aspheric parabolic mirrors with off-axis angles approaching 30 degrees and focal lengths as short as 100mm. They can also fabricate high-performance aspheric lenses with tight tolerances. Excellent performance is achieved with low surface scatter (20-10 scratch-dig) and high surface accuracy (lambda/20). The complex surface profile of aspheres offers excellent correction of spherical aberration and reduces other optical aberrations compared to a simple lens or mirror. On-axis parabolic mirrors produce collimated reflected light and are used in applications that require very fast focusing and high energy densities. Off-axis parabolic mirrors provide an unobstructed aperture allowing complete access to the focal region.

Machine Vision Camera System

Toshiba Teli America (Irvine, CA) has introduced the CS8581QF, a remote-head FireWire camera system for high-speed industrial imaging. The CS8581QF offers 133 fps at full 640 × 480 resolution (8bit monochrome), and partial scan modes over 430 fps. Based on a 1/3-inch progressive scan CCD, the CS8581QF features 7.4μm square pixels, an electronic shutter (1/50,000 to 2 sec), and random trigger shutter. The CS8581QF is comprised of a remote head camera and a central control unit (CCU) that can be mounted up to 2 meters apart from each other by a cable.

Sub-Miniature Resonant Optical Scanner

The SC-3 Sub-Miniature Resonant Optical Scanner from Electro-Optical Products (Fresh Meadows, NY) is an electromagnetically driven moving mirror device that deflects a light beam with a continuous sinusoidal motion. The scanning frequency range is from 100 Hz to 1000 Hz, fixed at any one value within the range. High device “Q” insures frequency stability, low reaction forces, and low electrical drive power. High flexural stiffness provides good resistance to shock and vibration, as well as low wobble, and good scan repeatability.
