IPC: H01S5/00
Filed: 1991-02-15
Abstract: PURPOSE:To measure the projecting power correctly with removing the returning light of a semiconductor laser, and without breaking the semiconductor laser while the semiconductor laser is APC driven. CONSTITUTION:An adapter 4 is mounted to a head 1 which measures the optical output, and is provided above an objective lens 12 of a pickup.

Title: Zoom lens
Inventor: TAKAHASHI SADATOSHI
IPC: G02B15/163
Filed: 1986-02-28
Abstract: PURPOSE:To obtain a lens system of high performance which is satisfactorily compensates for various aberrations and has about F2.8 aperture ratio, by forming one face of the third lens group, which is fixed when the power of the lens system consisting of three lens groups is varied, into an aspherical surface and setting a specific conditional inequality with respect to focal lengths. CONSTITUTION:The lens system consists of the first group having a negative refracting power, the second group having a positive refracting power, and the third group, which is fixed in case of variable power and has a positive refracting power, arranged in order from the object side, and the second group is moved linearly and the first group is moved nonlinearly in case of variable power from the wide angle end to the telephote end. The variation of the astigmatism and the Petzval..s sum due to zooming are compensated by the third group whose concave is directed to the object side, and one face of the third group is formed into an aspherical surface to extend the field angle while compensating the astigmatism accompanied with variable power. If a ratio of focal lengths is lower than the lower limit of the conditional inequality I setting focal lengths, the back focus is made shorter; and if it exceeds the upper limit, the refracting power of the second group is weakened to make the lens system large-sized. Thus, the lens system compensates various aberrations well and has about F2.8 aperture ratio and has a high capacity.
