Title: Laser tube
Inventor: HATSUDA YOSHIO
IPC: H01S3/032
Filed: 1987-11-21
Abstract: PURPOSE:To lengthen durability by mounting a low-temperature suction means for vapor at a position deviated from a central axis in a cylindrical body to be fitted. CONSTITUTION:Optical windows 62, 63 are sealed and installed outside each electrode section 52, 53 for applying voltage through cylindrical bodies to be fitted 60, 61. The cylindrical bodies to be fitted 60, 61 are composed of stainless, and a low-temperature suction means 1 for vapor is mounted at a position deviated from a central axis in the bodies to be fitted 60, 61. The suction means 1 is constructed of a metallizing suction member 1A properly sucking metallizing and a water cooling mechanism 1B cooling the member 1A at all times, and cooling water used for the water cooling mechanism 1B is fed in from outside, and made to flow out to the outside. The suction member is held at a low temperature by cooling water, etc., and large temperature difference is set to the optical windows 62, 63, thus quickly sucking the metallizing of a laser working substance in a laser tube and the vaporized substance of a capillary and a heat-insulating section to the suction member. Accordingly, the blooming of the optical windows 62, 63 is reduced remarkably by the evaporation of these substances, thus diminishing the absorption and scattering of laser beams.

After alignment, a sight line fixing beam of light is projected on the eye of the patient from the window 36, and thin beams of light of four power sources are also projected. These four beams of light are obliquely converged toward the optical axis, and cross a curved surface of the eye at a point surrounding a sight line fixing line.  Respective light spot images relected from the cornea are received by an imager of an image in the keratometer 10 through the window 36, and an electric signal in proportion to incident light intensity of respective pixels is generated, and an interval between reflected light spot images is electronically derived. A built-in processor controls these measurements, and displays (32) them by calculating measured values of a radius of curvature, a major axis angle and a minor axis angle of the cornea.
