Abstract: An optical measurement apparatus includes a thermal insulation housing, a first light-transmissive plate, a second light-transmissive plate, a heat-conductive layer, a cooling source and a photosensor. The thermal insulation housing, the first light-transmissive plate and the second light-transmissive plate define a chamber. The heat-conductive layer is disposed in the chamber, the cooling source is coupled to the heat-conductive layer, and the photosensor is disposed outside the chamber and on one side of the second light-transmissive plate facing away from the first light-transmissive plate.

Abstract: An optical lens includes an aperture, a first lens, a second lens, a third lens, and a fourth lens sequentially in a direction. One of the first lens and the second lens has positive refracting power, and the other has negative refracting power. The third lens has refracting power, and is a lens with a largest diameter in the optical lens. The fourth lens has the refracting power. The four lenses are made of glass. For light having a wavelength of 1315 nm, a transmittance of the optical lens is greater than ninety percent.

Abstract: An optical lens includes a first lens group, an aperture, and a second lens group which are sequentially arranged along an optical axis from a magnified side to a minified side. The first lens group has a negative refractive power and includes three lenses with refractive powers. The first lens group includes a lens with positive refractive power. The first lens group includes an aspheric lens. The second lens group has a positive refractive power and includes three lenses with refractive power. The second lens group includes a lens with a negative refractive power. The second lens group includes a lens closest to the minified side which is a cemented lens. The second lens group includes an aspheric lens. In the optical lens, a number of the lenses having the refractive powers is within a range from 6 to 8.
