IF-PM: Digital Photometer: (Optical Power Meter)
IF-PM200: Optional Range Model: 199µW, 1.999mW, 19.99mW, and 199.98mW

A versatile and economical classroom tool for measuring power levels of laser beams, and demodulating optical signals for audio applications and solar experiments. Photometers are essential equipment in any principles-of-technology or in-school research program. The battery power, portability and adjustable height detector of this model offer particular flexibility.

The photometer is powered by two standard 9-volt batteries and offers four digital measurement scales from 20 microwatts through 20 milliwatts. Output to two industry-standard banana jacks is a conditioned electrical voltage that is directliy proportional to light incident upon the photodetector with a frequency range up to 10kHz. (The analog output can be connected to a strip chart recorder for solar monitoring, to an oscilloscope for observing time-dependent optical signals, or to an amplified speaker for voice transmission.) The photometer also will act as an audio receiver to demodulate laser signals, which are also output to industry-standard banana jacks.

Features:

• Large easy-to-read digital display
• Four measurement scales from 20 microwatts tyo 20 milliwatts
• Large active area detector
• Sensitive to visible and IR light
• Battery loperation for portability (100-plus hours operation)
• Momentary switch for long battery life
• Adjustable detector height
• Impact resistant enclosure
• All solid-state detector and electronic design

IF-551: Cylindrical Lens Set

High quality acrylic lenses designed for use with the Laser Ray Box. Specially formulated material allows the visualization of laser beams traveling through optical element. Allows the direct observation of refraction, Fresnel Reflections and internal reflection within the optical element itself. Set includes four 20mm thick optical elements listed below:

• Double convex, 50mm, focal length 50mm
• Double convex, 76mm, focal length 10mm
• Right Angle Prism, 70mm on oblique side
• Rectangular Block, 70mm x 28 mm

IF-XYP: X-Y Pattern Generator

The X-Y Laser Pattern Generator is the creative educational vehicle to captivate student interest in the dynamic world of laser technology. When used with any laser, this device creates endless combinations of patterns and shapes, similar to those created for large and expensive laser light threatrical presentations.

Applications:

• Create students' own laser light shows
• Dynamically contrast stereo and mono audio sounds
• Mimic the use of laser beams in cutting applications
• Meet the special lighting needs of small theaters
• Demonstrate laser beam control with motors and mirrors
• Create infinite numbers of "Lissajous" and quadrature patterns

The generator is housed in a see-through cool-blue acrylic case for easy viewing and alignment, and can be used in conjunction with any HeNe, diode or visible light laser. Laser light patterns can be generated with either the internal electronics or patched to an audio signal to create light images from sound.

(Pattern Generator comes with control head, 110Vac-to-12Vdc power adapter and operator's manual. An external lasting source is required).
