Laser 630nm (Each)

SKU: XLL010010 Categories: ,

This laser emits an intense monochromatic red beam of wavelength 630-640nm at
0.9mW (Class II operation). Typical beam divergence is approximately 1
millirad. The laser is ideal for the demonstration of the behaviour of light
in a visually effective way, reinforcing the practical work carried out by
pupils using white light. It is an essential tool to develop basic
understanding of the passage of light through different media, slits etc. The
laser beam can be modulated by applying an external digital or analogue
waveform to the 3.5mm jack socket on the rear panel. Alternatively the beam
can be modulated by the internal generator which produces 0.1êž³ pulses at
approximately 1MHz. This allows speed of light experiments to be easily
performed. The passage of light through light guides and optical fibres can be
demonstrated by filling a glass or plastic tube or U-tube with very dilute
milk. The growth of laser based communication systems and research into the
use of lasers in computers of the future, makes this an essential piece of
equipment to bring up-to-date relevance into teaching. The laser is powered by
a 6LR61 (PP3) battery or external smoothed and regulated supply, has
adjustable focus, no warm up time and has a key operated safety switch. Housed
in a robust anodised aluminium case. Supplied with key. Dimensions: 55 x 150 x
65mm Mass: 0.4kg
