Abstract
The utility model directs to a focal length measuring meter pertaining to the optical experimental instrumental equipment. A telescope (1) is securely connected with a 4-dimension adjusting platform (4). The 4-dimension adjusting platform (4) is connected with a guide rail (5). A 3-claw disc (2) and a parallel light tube (3) are positioned on the guide rail (5). The utility model has the advantages of a compact structure, a reasonable layout and a high experimental precision.
Description
Technical field
The utility model belongs to a kind of optical experiment instrument equipment.
Background technology
At present, the most of institution of higher learning of China and scientific research institution are during for parameters such as the focal length of measurement lens, intercept, camera lens resolution, some all purpose instruments of can only temporarily arranging in pairs or groups are measured, and do not have a whole set of complete instrument available, and the accuracy of measurement result is lower.
Summary of the invention
The utility model provides a kind of focimeter, has solved the lower shortcoming of accuracy of prior art measurement result.The concrete technical scheme that the utility model is taked is: telescope 1 is fixedly connected on four-dimensional the adjusting on the platform 4, and this four-dimension is regulated platform and is connected with guide rail 5, and scroll chuck 2 and parallel light tube 3 are fixed on the guide rail 5.During use, lens are clamped on the tri-claw disk 2, and regulate telescope 1, scroll chuck 2 and the four-dimensional platform 4 of regulating, make and in telescope 1, see striped picture clearly, at this moment measure the spacing of each striped,, just can calculate the focal length of these lens the value substitution focal length computing formula that records.
Advantage of the present utility model is: compact conformation, and rationally distributed, the measuring accuracy height.
Description of drawings: accompanying drawing is a structural representation of the present utility model.
