LASERTECHNOLOGY & EQUIPMENT

Digital Photometer

Industrial Fiber Optics

Measures power levels

of laser beams, demodulating optical signals for

audio applications and solar experiments. Offers

4 scale measurements from 20 microwatts to 20

milliwatts. Battery power, portability and adjust-

able detector height offers flexibility.

Analog output to 2 banana jacks is a conditioned electrical voltage that is

directly proportional to light incident upon the photodetector with a fre-

quency range up to 10 kHz. This allows it to be connected to a strip chart

recorder for solar monitoring, oscilloscope for observing time-dependent

optical signals or to an amplified speaker for voice transmission. Meter will

also act as an audio receiver to demodulate laser signals.

• 4 ranges

• All solid state detector & electronic design

• Calibrated at 632.8 Nm • Sensitive to visible & IR light

Includes

metal optical stand, manual, two 9V batteries & case.

Laser Optics Lab

Industrial Fiber Optics

Laser optics lab con-

tains more than 30 optical parts and accesso-

ries. With the lab components and instructions,

students can:

• Measure wavelength of light using techniques of Young, Michelson & Lloyd

• Constrict optical levers to detect & measure movements so small they

are almost imperceptible to the human eye

• Test a lens for defects, collimate light & check vision

• Capture light in an arcing water jet or a glass fiber & investigate fiber op-

tics phenomena

• View a hologram, observe interference rings & measure the diffraction

patterns with a ruler

• Determine index of refraction of a liquid or transparent solid by measur-

ing bend in intense laser beam as it enters or leaves material

• Investigate reflection, refraction & critical angle

• Study characteristics of light: wavelength, interference, diffraction & polarization

Includes

optics bench system

(metal component carriers that attach mag-

netically to steel optical table)

, 3 lenses, 4 mirrors, coated beam splitter, tri-

angular prism, beam spreader, air wedge, transmission hologram, diffraction

mosaic, diffraction grafting, fiber optics light guide, pair of glass interference

plates plus polarizing & color filters, plus 68-page manual.

Helium-neon Lasers

Industrial Fiber Optics

Provides 20,000

hours of continuous operation. For individual

student lab work or hands-on group demon-

strations. Rugged extruded aluminum housing

contains laser tube and all power supply

components. Has standard 1/4" camera-type threaded hole in bottom for

tripod or optical bench mounting. Threaded optics mount over front ap-

erture to facilitate mounting lenses, filters or collimators. Slide shutter over

front aperture blocks beam without having to shut off power

(as required

by US CDRH)

.

• Rear end cap w/power switch & indicator lamp, fuse holder & line cord

w/3-prong grounded plug

• Hard-seal laser tube ensures long, dependable life

• Solid-state power supply mounted on printed circuit board

• Labels & safety features to meet all US CDRH regulations

• Shock-resistant mountings

• Full-length rubber strips along bottom

Class II Laser 0.5 mW

Ideal for individual work in the student

laboratory or for group demonstrations. Power requirements: 105-

125VAC, 30 watt.

Class II Laser 0.8 mW

Same as ML800 but w/output power of

0.8 mW. Beam is visible in bright or semi-darkened room of average

size, but to see fine details in diffraction pattern or make holograms or

precise intensity measurements of laser output, a relatively dark room is

suggested.
