ST-194 optical resin lenses-Table 5

In the various types of monitoring (infrared, laser, etc.) devices, the transmitter, which emits the light beam actively, almost uses a lens. In order to reduce the size of the transmitter and obtain good light gathering, a shorter focal length of this lens and high image quality are required. Therefore the aspherical lens is generally used. This lens is one example. Its parameters are as follows:

Focal length f'=7.661mm

Front intercept sf=-7.661mm

No.
