When a photographic ocular is changed, there is also a change of the marked field on the reticle (image field marking plate) on account of the change in magnification. The metering field marking plate is defined by a metering field stop, and the two markings, which differ in shape and size, are reflected simultaneously be means of a photographic ocular located in the picture-taking beam and by optical components arranged ahead or behind the photographic ocular and comprising partly or wholly specular surfaces. Markings for the metering field and for the image field are mounted on two separate plates. 4,118,719 discloses an attachment camera for microscopes having an observation beam with a system for measuring the brightness of an object detail and with markings for sighting at least the detail metering field and the image field of the camera in the observation beam.
4,118,719 is incorporated herein because the present invention is an improvement thereover and like components are designated with the same reference numerals. The state of the art of microscope attachment cameras may be ascertained by reference to U.S. The field of the invention is photography combined with the compound lens system of a microscope and the invention is particularly concerned with a microscope attachment camera with exposure metering for the photographic recording of an object or detail of same. P 29 24 053.7 filed Jin the Patent Office of the Federal Republic of Germany. The microscope and attachment camera of claim 1, wherein said photographic ocular is a zoom ocular.Īpplicants claim priority under 35 USC 119 for application No.
The microscope and attachment camera of claim 3, wherein said housing (24) has means for supporting both said attachment camera and said holding means for rotation about said imaging beam (28).Ħ. The microscope and attachment camera of claim 3, wherein said housing (24) has means for supporting said attachment camera for rotation about said imaging beam (28).ĥ. The microscope and attachment camera of claim 1, wherein said holding means (5a) having a camera side region and an object side region comprise an annular attachment rest surface (29) at said camera side region and an annular attachment rest surface (27) at said object side region and a tubular photographic stub (26) mounted on said binocular tube (25) having a hollow cylinder geometry corresponding to the attachment rest surface (27) for partly seating said holding means (5a).Ĥ. The microscope and attachment of claim 1, wherein said holding means (5a) has means for detachably joining said holding means to said housing (24).ģ.
Said holding means connected to said housing for simultaneous rotation therewith whereby said object detail is aligned with said image field marking without rotation of said object.Ģ. Holding means (5a) seating in exchangeable manner said photographic ocular (5) provided between said housing (24) and said binocular tube 25 and In a microscope and attachment camera therefor having an observation beam with a system for measuring the brightness of an object detail and with markings for indicating at least the detail metering field and the image field of the camera in said observation beam, wherein a metering field marking (14) is positioned on a first plate and an image field marking (22) is positioned on a second plate, said first plate defined by a metering field stop (14), said metering field marking and said image field marking differing in shape and size (14,22) and being simultaneously reflected into said observation beam through a photographic ocular (5), said photographic ocular having an imaging beam (28) passing therethrough, the improvement comprising:Ī housing (24) for said attachment camera, at least one binocular tube (25) on said microscope
