For rapid examination of spectral composition of white light. Consisting of metal tube with draw out focussing and an adjustable slit fitted with achromatic objective glass and element prism.

This direct vision spectroscope incorporates fine slit in conjunction with an efficient blazed grating, which transmit high proportion of energy into the first and second order spectra, giving very bright and sharp spectra. The third order spectra can also be seen, although not as brightly.

Spectroscopy is an interesting visual subject for students. This spectroscope helps teachers to demonstrate simply and clearly. Uses include; •Fraunhoffer lines •Flame test in chemical analysis •Absorption spectra through liquids •Bright line spectra from discharge tube Features; •Large diameter eyepiece aperture facilitates comfortable viewing of the single, large and bright spectrum which is centrally placed in the field of view •High quality optical components ensure that absorption bands show up clearly – even weak bands that are sometimes difficult to detect •The spectrum is generated by a particularly bright transmission diffraction grating of 600 lines/mm •Fixed construction – no need for adjustment •Robust assembly to withstand years of student handling •Benchtop size: 105 mm x 25 mm •Boxed weight: 115 g •Supplied in a protective rigid box

The performance of this ultra-low cost spectroscope is comparable with instruments costing much more. It uses a CD or DVD as a reflective diffraction grating and clearly shows Fraunhofer lines in the spectrum arising from natural light, distinctive emission bands from artificial sources such as sodium lamps and differences between different types of fluorescent lighting tubes. The spectroscope is made from polypropylene and supplied in flat pack form for quick self-assembly. It comes with free CD but can be used with any CD (or DVD for higher resolution).

An economically priced instrument, which is nevertheless capable of much useful quantitative work. The main structural parts, including the collimator and telescope bodies are heavy castings, other metal parts being bright plated. SCALE: 170 mm dia. divided to 360° 1°, independently rotatable with locking screw. spring-loaded vernier scale attached to the telescope mount provides readings to 0.1° (6 minutes of arc). COLLIMATOR: Mounted on a fixed pillar with axis adjustment. Objective lens 150 mm FL, an aperture of 21 mm and is carried in spiral focusing systems. Unilaterally adjustable slit 6 mm long. TELESCOPE: Mounted on moveable pillar with adjustment, locking screw and axis adjustment. Objective lens has 170mm FL, 21mm aperture and is carried in spiral focussing system. RAMSDEN EYEPIECE: With cross wires and locking ring focus adjustment. PRISM TABLE: The table is provided with three leveling screws and is line marked to assist placement of prism. STANDARD ACCESSORIES SUPPLIED: 1 prism clamp for prisms up to 40 mm high, 1 diffraction grating holder, aperture 25 x 25 mm, 1 small screwdriver, 1 tommy bar for axis adjustment and case.

This laser emits an intense monochromatic red beam of wavelength 630 nm at 0.9 mW (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 3.5 mm jack socket on the rear panel. Alternatively, the beam can be modulated by the internal generator which produces 0.1 µs pulses at approximately 1 MHz. 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 make 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.
