A thick lens or prism with at least one spherical shaped surface is utilized in conjunction with a glass fiber delay line to create a sensitivity, boresight and range accuracy test unit for a laser rangefinder, which test unit may be built into the laser rangefinder. This test unit performs laser rangefinder sensitivity and boresight tests in a small volume with relatively simple components having a minimum of weight making its incorporation into most laser rangefinders very practical.
