- New C.B. Lantern
- The New “ C.B.” Projection Lantern is an instrument designed principally for use in schools, where simplicity of operating, sturdiness of design and absolute reliability are essential.
- The lantern is built on two rails after the principle of an Optical Bench and this ensures the different components being always in line. The objectives of 6in., 8in. and lOin. focus are of lfin. aperture and 2fin. aperture in the longer focal lengths up to 18ins., and all are mounted in helical focussing mounts. They are of the best quality and give critical definition. The condensers are easily accessible and can be removed and cleaned, when necessary, without any difficulty.
- A simple tilting device is provided for rooms in which the screen is higher than the lantern. The slide carrier is of the automatic lifting type.
- Most interesting is the design of the lamphouse. For some time our projection apparatus has been noted for its coolness and this model is no exception. The lamp-house is built with two walls. Between the two lamphouses cool air is always circulating, so that the outside lamphouse remains quite cool to touch, even when high wattage lamps are being used. The importance of this coolness will be evident to anyone who has touched the body of the usual type of lantern in the dark by mistake after it has been burning for some time.
- The lamp adjustments are simple and give adequate movement in all directions.
- The instrument will close into a small space for storing, but in spite of this compactness, an extension of 16ins., or more is obtainable on the standard instrument, and lenses from 6in. to 14in. focus can be used. The lantern can be made with a longer extension, however, if it is desired to use longer focal length lenses than this.
- The New " C.B.” Lantern is finished in crystalline enamel and nickel-plated, and is as attractive in appearance as it is efficient in practice.
- Price with 6in., 8in. or lOin. lenses of lfin. aperture, without lamp Lenses of 2fin. aperture of longer focus than lOins., without lamp 500 watt Lamp 250 „

- Research Microscope Lamp
- n
- The employment of the 6 volt 4-5 ampere bulb lamp has enabled a Microscope Lamp with a very intense illumination to be produced for Photomicrography, and especially Dark Ground Illumination.
- An optical glass rod is fitted in the front of the lamp housing, one end is polished and the other ground. It is from this latter end that the illumination is obtained. By altering the distance between the polished end and the bulb, varying intensities of light can be obtained. On the front of the rod is fitted a plate for carrying coloured filters, and this can be replaced by a right-angle prism for reflecting the light direct into the Substage Condenser or Dark Ground Illuminator. The prism can also be used for illuminating opaque specimens on top of the stage.
- For alternating current a transformer is provided fitted to the stand, as illustrated ; this also adds to the stability, but for direct current it is necessary to provide a variable resistance.
- All necessary movements are provided and the upright is high enough to enable the rod to illuminate the top of the stage of most modern microscopes.
