Ray Box

Ray Box To provide a simple means of producing single or multiple rays of light for use in elementary optics. Ray box is a metal ventilated lamp house having an open front with extended sides finned externally for heat dissipation. Ray boxes will produce good rays, but they tend to emphasize parallel incident rays. Used with a multi-slit comb. This apparatus produces a broad fan of ray streaks. The Ray box is a die cast ventilated lamp housing. It has an open front with extended sides, finned externally to promote heat. Dissipation and vertical internal grooves to accommodate a slit plate and a cylindrical lens supplied with complete lamp & triple slit, but without lenses of filters. Used in elementary optics to provide single or multiple rays of light for use.....

Ray Box

Ray Box  Designed with two slots to hold blanking plates, seven grooves for lenses.  Used for a wide range of optics experiments with this high quality, robust ray box.  Only a minimum of accessories are needed to cover a wide range of optics experiments.  Supplied with 12V, 20 - 24W, bulb, holder, slit plates, blanking plates and instructions. The two side openings each havetwo slots for accommodating blanking plates, 50 mm slide accessories.  This traditional Ray box has three openings, two of which can be used simultaneously by two sets of pupils.  Supplied with 2 meter of flex and two 4 mm plugs, 12 V, 24 W B 15 bulb, bulb holder, slit plate, aluminium blanking plates. A front opening provides seven grooves for accessories and lenses which have been designed so that when used with a biconvex cylindrical lens of 75 mm focal length, divergent or convergent rays are obtained through the slit plate. ....

Ray box Mirrored with accessories Lateral aperture is provided with adjustable hinged mirror.  This kit is very useful for reflection, refraction and colour mixing experiments. All apertures in the box are provided with vertical channels to hold slit-plates and color filters.   The Mirrored Ray box consists of a light source (12 V, 24 W lamp) producing a convergent, divergent or parallel beam.  On one end there is an adjustable cylindrical convex lens (for parallel beam) and a triple aperture system for color mixing experiments at the other end.....

Ray box Slit Plates

Ray box Slit Plates Strong plastic construction with 3 apertures.  Plus 2 blanking plates for unsused apertures. 12 V 24 W. Supplied with 2 slit plates with one & two slits, and 3 & a wide slit. ....

Ray box with Accessories

Ray box with Accessories The raybox can be used in a single-ray mode without using the plano-convex lens. The light source is mounted under an adjustable lid, designed so that minimum light emerges in unwanted directions.   These facilities enable the ray box to be used in a wide range of optical experiments with transparent flatbased blocks, prisms and mirrors. The coloured filters can be used to produce beams of coloured light, but external light levels have to be reduced for maximum effectiveness.  However, with the lens inserted (plane face towards the light source), and using the two-slit, three-slit or broad-slit masks, the emergent light can be made to be divergent, convergent or parallel by adjusting the position of the light source in relation to the lens.  Base measurements: 180 x 65 x 75 mm.  Power requirement:  12 V (AC or DC) connected to two 4 mm sockets on the ray box.  Light source:  12 V, 10W line-filament bulb, length 43mm.  Accessories: Plano-convex lens of focal length 75 mm; 2 plastic masks with, respectively, one and two thin slits, three thin slits and one broad slit; 7 colored filters and 1 tri-color filter, mounted in 50 x 50 mm plastic frames;....
