The invention relates to a device and a method for automatic
surface scanning and measuring of a transmitted spectrum of an optical element. The device comprises a
light source, a light diaphragm, a first convergent mirror, a monocolor
system, a collimating lens
assembly, a second half-reflection pellicle mirror, a reference path, a measuring light path, a third half-reflection pellicle mirror, a second convergent mirror, a sample to be tested, a
signal receiving
system and a computer. The device and the method are characterized in that the measuring light path measures the horizontally-placed sample to be tested; and the computer is provided with
control software, and is connected with a first half-reflection pellicle mirror, the second half-reflection pellicle mirror, the third half-reflection pellicle mirror, the monocolor
system, a two-dimensional electric translational platform and the
signal receiving system respectively through
signal wires. The method realizes the transmitted spectrum measurement of the optical element, can measure the optical element with the
maximum dimension of 400 mm x 600 mm, and realizes the automatic
surface scanning and measuring of the optical element through the control of the
control software of the computer.
