Nd:YAG lasers
The Y70S series of OEM, industrial, diode-pumped Nd:YAG lasers uses a longer cavity to produce a stretched pulsewidth and lower-peak power for high-precision materials-processing applications. It delivers >6.5 W at 1064 nm with repetition rates up to 100 kHz, with M2<1.2. In harmonic generation, it has an average power of >3 W at 532 nm. The modular design with self-aligning connectors allows in-field replacement as well as automated control of the doubling harmonic module.

Linear slides
Series 1 double-rail linear sliders feature two sets of recirculating linear bearings mounted to a 3 x 21/2-in. saddle plate for backlash-free operation. They are available in 14 lengths from 300 to 3000 mm. The rail assembly consists of two hardened and ground 12-mm-diameter rails bolted to a 36 x 28-mm aluminum profile. Saddle plates measure 75 x 75 or 75 x 125 mm. The assembly has a position repeatability of 0.01 mm/m.

Laser diode
The DL-4038-026 laser diode has a maximum CW output of 25 mW at 635 nm and monitoring output current of 0.2 mA. It is made of AlGaInP using misoriented substrate and multiple-quantum-well active layer. The laser comes in a 9-mm (TO-5) package with an operating temperature range of -10°C to 40°C. It has a typical operating current of 70 mA, operating voltage of 2.3 V, and requires a positive (N type) power supply. The device is suitable for laser levelers, laser scanners, and optical measurement equipment.

Turning mirrors
A line of laser turning mirrors and reflectors can be used in dirty industrial environments with carbon-dioxide lasers emitting at 10.6 µm. Available are molybdenum mirrors that have >98% average reflectance at a 45° angle of incidence and that can withstand frequent cleaning due to their intrinsic hardness. Silicon turning mirrors come with enhanced silver or DBMR dual-band coatings with 99.5% and 99.7% average reflectance. Silicon and copper phase retardation reflectors have <1.5% absorption.

Nitrogen-purged measurement system
The Purged CAMS Spectrophotometer, designed primarily for use with 157-nm deep-UV optics, will measure reflectance and transmission of high-performance optical coating in the same nitrogen-purged environment to which they would be exposed in 157-nm deep-UV lithography systems.

TE-cooled PIN photodiode hybrids
A compact thermoelectrically (TE) cooled PIN photodiode hybrid assembly has been introduced for high-precision, low-light-level detection applications. The device consists of a large area (33.3 mm2), low leakageX, silicon PIN photodiode, and a low noise, high-gain transimpedance preamplifier, mounted on a single substrate and temperature-controlled by a two-stage TE cooler. It is housed in a hermetically sealed TO-3 can.

Miniature convergent-mode sensors
The new VS2 Series Convergent-Mode Sensors are self-contained miniature sensors (measuring 25.1 x 12.0 x 3.6 mm) allowing access to confined areas previously accessible only to fiberoptic or remote-sensing devices. The sensors utilize a visible red sensing-beam to provide a 15- or 30-mm range, depending on model, and repeatability of 160 µs with an output response time of 1 ms. Applications include small machinery, microelectronic handling equipment, vibratory feeders, and punch presses.

High-speed optical pickup unit for CD-RW drives
The Blue Sky Research OPU is an optical pickup unit for CD-RW drives that is designed and produced in the USA. This high-speed OPU delivers 8x/8x/32x write/rewrite/read speeds in a lightweight, compact package designed for desktops and multimedia peripherals.
Blue Sky Research, San Jose, CA

Optical modeling software
The newly released Advanced Systems Analysis Program version 7 software for optical-systems analysis has been enhanced in response to customer requests. Enhancements include finite-difference wave-field propagation; volumetric energy tracking; inhomogeneous Monte Carlo volume-scattering; expanded bidirectional scattering; distribution-function fitting capability; and an updated user interface, including a fully integrated 3-D viewer.

Low-noise preamplifier
The model PAPY series is a miniaturized low-noise preamplifier designed for remote placement and operation of pyroelectric detectors for use with FTIR spectrometers. When considering the return fiber's attenuation (to the spectrometer), the unit has the sensitivity and noise performance to replace a LN2-cooled MCT detector in many applications.
Barnes Engineering, Shelton, CT

4-kHz Argon-fluoride laser
The NanoLith 7000 is an argon-fluoride production laser designed for lithography applications at 193 nm with a low cost of operation. The laser has a repetition rate of 4 kHz and enables the production of devices with .10-µm and smaller geometries.

Optical transceiver module
The miniature integrated Optical Network Unit, OD-B1511-ONU from NEC, was developed for use in customer premise equipment in FTTH and FTTB transmission systems. The transceiver modules have onboard feed-forward circuitry that monitors and adjusts for temperature changes, maintaining consistent power to the laser diode.

Optical layout software
OLIVE (Optical Layout Including Video Elements) is a newly introduced optical layout software package that simulates the optical bench on any computer running Windows 95/98/00 or NT. Users may grab, add, or move the lenses with the mouse, and OLIVE traces the rays in real time. Features include the calculation of chromatic and seidel aberrations, identification of limiting apertures and field stops, and the ability to customize and save lens designs. OLIVE designs may be exported to Zemax or Code V formats for optimization.

CO2-laser drilling system
The Model 5380 CO2-laser microvia drilling system is designed for the high-density interconnect market widely used in mobile telecommunications products. The system can produce more than 30,000 vias/min in single-layer laminated materials and is equipped with a compound beam positioner to eliminate stepping time and abutment errors during drilling.
