Similar to 3380-00 but with enhanced features for obtaining better quantitative results. Consists of a heavy cast base and a pillar for collimator support. The telescope arm moves along a fixed circular plate 150mm diameter graduated in degrees. This plate has a double ended vernier for better and accurate measurements, with a least count of 30". Fine adjustment is accomplished by using a knob while the coarse adjustment can be done by hand. Both the collimator and the telescope are mounted with an axis adjustment system. The telescope has a 10X Ramsden eyepiece and is fitted with a cross hair reticle. Both the telescope and the collimator are fitted with coated achromatic objectives of 178mm focal length and 32mm diameter, providing light for a brighter and sharper image. The focussing is done by a concealed rack and pinion. The collimator slit 6mm long, is specially designed for retention of initial accuracy during the life of the instrument. The prism table 75mm diameter is held with the help of a clamping screw enabling the table to be rotated in any direction. It has lines and concentric rings marked to assist positioning of prism in relation to levelling screws.

Prisms have several uses in optical systems. For example they can deviate a ray, disperse white light into the visible spectrum or erect an inverted image. Right angle prisms 90º-45º-45º are used for accomplishing a 90º bend due total internal reflection. Depending on the mode of incidence of light on the inclined face, this prism may have an inverting effect with or without deviation. |

Periscopes, including this one, can help you see around barriers. But what if you want to see something behind you? Submarine periscope operators walk in circles, turning the whole periscope. Why not just rotate the top mirror? Try it with this rotating periscope, and you’ll see that the image of everything behind you is upside-down! An elegant demonstration of basic plane mirror reflection, this is also a great way to test student understanding of image formation. |
