The width of a slit S for a spectrophoto-meter is so controlled that the intensity of the radiant energy which passes to the detector is kept substantially constant irrespective of the wavelength and is also adjustable so that the level of intensity may be varied. As shown a cam 26 is rotated by a wavelength driving mechanism (not shown) and this causes, through cam-follower 25, sliding movement of a rod 21 which is rigidly connected by a bridge 24 to a second sliding rod 22. A block 20 which is pressed by springs 27, 28, towards a screw 29 on the block 24, carries a cam-follower 19 engaging cam-surfaces 15, 16, on a pair of pivoted levers 10, 11, supporting the slit jaws 13, 14. Consequently the movement of jaws 13, 14, is controlled by rotation of cam 26 but the setting of the jaws 13, 14, for any particular position of cam 26 may be varied by adjustment of the screw 29.

    Abstract: 1,093,294. Spectrophotometers. SHIMADZU SEISAKUSHO Ltd. June 15, 1966 [June 15, 1965], No. 26699/66. Heading G2J. [Also in Division G1] A spectrophotometer, having a radiation source, an entrance slit 24, a collimator 25 and two diffraction gratings G1, G2 rotatable about their own axes so as to form partly overlapping ranges of wavelengths, is provided with a mirror M which is movable into or out of a beam of light from the collimator 25 for selectively directing the beam towards each grating, movement of the mirror being effected when the two gratings G1, G2 are arranged to produce the same wavelength within the overlapping portion of the respective wavelength ranges. In the embodiment shown each grating is mounted on a shaft 32, 33 which also carries a lever L1, L2. The levers L1, L2 are urged against cams C1, C2 respectively. The cams C1, C2, together with further cams C3, C4, C5, are fixedly mounted on a shaft 34, driven by a motor 35. The third cam C3 actuates a micro-switch 41 to start a motor 40. The mirror M is moved by a belt 42 which is driven by the motor 40, an actuator 43 fixed to the belt being provided to actuate one of two microswitches 44a, 44b and so stop the mirror M. Light diffracted by the gratings returns to the collimator 25 and is then directed through a slit 27 on to a detector 31. Any unwanted frequencies of the diffracted light passing through the slit 27 are removed by the location in the light path of one of a selection of interferences filters F1, F2, F3, F4 mounted in a rotatable disc 45. A motor 46 rotates the disc 45 on actuation of one of two micro-switches 47, 48 by the co-operating cams C4, C5 respectively. Further micro-switches 49-52 are actuated by a projection 53 on the disc 45 in order to stop the motor 46. The cams C1-C5 are shaped so as to produce the required sequence of movements on actuation of the motor 35. With the mirror located in the light beam as shown, rotation of the cam C1 causes the grating G1 to scan a first wavelength range # 1 to # 2 . Cams C1 and C2 then cause the gratings G1, G2 to scan simultaneously an overlapping range # 2 to # 3 . During this operation the cam C3 operates the motor 40 to move the mirror out of the light path. Thereafter the grating G2 scans a further wavelength As to # 4 . The cams C4, C5 serve to change the filters F1-F4 as required.

    Abstract: PURPOSE:To allow transmitted light to pass through the same optical path even of input light has different wavelength by providing a parallel plane compensating plate which correct deviation of the optical path of the transmitted light of a beam splitter due to difference in wavelength. CONSTITUTION:The oscillation division type beam splitter 11 is supported in a case 10 at a 45 deg. tilt angle and the parallel plane type compensating plate 14 which is as thick as the beam splitter 11 is arranged symmetrically with the splitter 11. In this constitution, the transmitted luminous flux B of light from an optical fiber 18 is refracted again by the compensating plate 14 and collimated by a SELEOC lens 16 into parallel luminous flux, which is coupled with an optical fiber 19. Thus, the compensating plate 14 is provided, so refraction similar to that of the beam splitter 11 is caused even is there is difference in angle of refraction owing to the difference in the wavelength of the incident light, so the light after transmitted through the compensating plate 15 passes through the same optical path and is usable as light containing different wavelength.

    Abstract: PURPOSE:To transmit double signals without using a light source, a photodetector, etc., for a long wavelength area by combining optical directional couplers for demultiplexing and multiplexing light having the same wavelength and an optical demultiplexer/multiplexer for demultiplexing/multiplexing light having different wavelengths in accordance with the wavelength. CONSTITUTION:When electric signals S1, S2 are inputted to an optical transmitting equipment 1, electrooptic converters 3A, 3B convert the input signals into optical signals with wavelengths lambda1, lambda2 and send the optical signals to the optical demultiplexer/multiplexer 5. The optical demultiplexer/multiplexer 5 multiplexes these optical signals and sends these signals to an optical transmitting equipment 1' through an optical fiber cable 2. The equipment 1' converts the optical signals with the wavelengths lambda1, lambda2 into electric signals S1', S2' in the reverse process against said process. When electric signals S3', S4' are inputted from the external to the equipment 1', the same processing as said one is executed and electric signals S3, S4 are obtained from an optical transmitting equipment 1. When 780/880mm is selected as the wavelengths lambda1, lambda2, parallel multiplex transmission for four signals with different wavelengths can be executed.
