An optical system for use with a stereo video endoscope with a fixed, lateral viewing direction, including: laterally-viewing distal and proximal optical assemblies, similarly configured left and right lens system channels; the distal optical assembly couples incident light from an object space into the left and right lens system channels; the distal optical assembly includes an entrance lens, a deflection prism group and an exit lens in a direction of incident light; the deflection prism group includes first and second prisms in the direction of incident light; the first prism includes first entrance and first exit sides at an angle relative thereto; the second prism includes a second entrance side, a reflection side and a second exit side; and the first entrance side of the first prism and the reflection side of the second prism enclose an angle that is greater than a total reflection angle of the second prism.
An optical system for use with a stereo video endoscope with a fixed, lateral viewing direction, the optical system comprising:
A method of forming an optical system of a stereo video endoscope with a fixed, lateral viewing direction, wherein the stereo video endoscope comprises a laterally-viewing distal optical assembly and a proximal optical assembly, and wherein the proximal optical assembly comprises a left lens system channel and a right lens system channel configured similarly to the left lens system channel, and wherein the distal optical assembly is configured to couple incident light from an object space into the left lens system channel and into the right lens system channel of the proximal optical assembly, and wherein the distal optical assembly sequentially comprises an entrance lens, a deflection prism group and an exit lens in a direction of incident light, wherein the deflection prism group sequentially comprises a first prism and a second prism in the direction of incident light, wherein the first prism comprises a first entrance side and a first exit side at an angle relative thereto, and wherein the second prism comprises a second entrance side, a reflection side and a second exit side, wherein the method comprises:
A method for repairing a stereo video endoscope with a lateral viewing direction, wherein an optical system of the stereo video endoscope comprises a laterally-viewing distal optical assembly and a proximal optical assembly, and wherein the proximal optical assembly comprises a left lens system channel and a right lens system channel configured similarly to the left lens system channel, and wherein the distal optical assembly is configured to couple incident light from an object space into the left lens system channel and into the right lens system channel of the proximal optical assembly, and wherein the distal optical assembly sequentially comprises an entrance lens, a deflection prism group and an exit lens in a direction of incident light, wherein the deflection prism group sequentially comprises a first prism and a second prism in the direction of incident light, wherein the first prism comprises a first entrance side and a first exit side at an angle relative thereto, and wherein the second prism comprises a second entrance side, a reflection side and a second exit side, wherein the method comprises:
