Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with accompanying drawing description and specific embodiment:

[0026] A high-precision hollow prism reflector device includes first, second and third glass plates 1, 2 and 3, inner surfaces 1A, 2A and 3A of the first, second and third glass plates, and a prism support 4. The connection relationship is: the first, second, and third glass plates 1, 2, and 3 are bonded to each other, and the adhesive (photosensitive adhesive) can easily connect the first, second, and third glass plates 1, 2 to each other. , 3 Bonding into a hollow prism reflector. The first glass plate 1 and the second glass plate 2 are bonded by photosensitive adhesive, and the third glass plate 3 is bonded with the first glass plate 1 and the second glass plate 2 by photosensitive adhesive (the name of the photosensitive adhesive material is GBN-501), After bonding, irradiate with purple light to cure the photosensitive adh...

Abstract

The invention discloses a high precision hollow prism reflector, comprising glass plates and a prism support seat. The high precision hollow prism reflector is characterized in that the three glass plates are in adhesive connection with one another by adhesive bonding so as to form the hollow prism reflector; and after adhesive connection, the glass plates form the shape of a hollow cone, a first glass plate and a second glass plate are in adhesive connection by photosensitive adhesive, a third glass plate is in adhesive connection with the first and the second glass plates by the photosensitive adhesive, an UV Lamp is used for irradiating and solidifying the photosensitive adhesive, corresponding standard faces on the three glass plates are the inner faces of the three glass plates, and the prism support seat is in adhesive connection with the rear face of the standard face of the third glass plate by an epoxy resin adhesive. The invention has the advantages of simple structure and convenient use, the device has light weight and high precision, and the reflectivity of the hollow prism reflector on which film is coated can nearly be higher than 99 percent. The high precision hollow prism reflector is suitable for full-wave band measurement.

Description

technical field [0001] The present invention relates to an optical instrument, more specifically to a high-precision hollow prism reflector device, which is an improved solid corner cube prism, and is suitable for special use environments in aerospace, surveying and mapping fields, such as laser reflectors for artificial satellites , Aerospace pendulum measuring device, infrared measurement in amblyopia environment, measurement of various invisible spectra in the laboratory, etc. Background technique [0002] The corner cube prism is a tetrahedral cone-shaped prism composed of three mutually perpendicular reflective surfaces and a transmissive bottom surface. It is a special retroreflector. In an ideal situation, after the incident light beam is successively reflected by three mutually perpendicular reflecting surfaces, the outgoing light is parallel to the incident light, but in opposite directions. When the prism rotates around the center line passing through its apex, it...
