Device for testing an optic

摘要

A device for testing an optic which is mountable thereon and has a central axis extending in the longitudinal direction thereof, comprising a test image, a test image table for supporting the test image, a light source for lighting the test image via the optic mountable thereon, an attaching device for mounting the optic mountable thereon, detection means placed on the attaching means for detecting the lighted test image, first guide means and second guide means co-acting with the first guide means and extending in longitudinal direction thereof for the purpose of positioning the test image table along a substantially straight line relative to the attaching device, and a signal processing device for receiving, storing and comparing detection values of the lighted test image detected by the detection means to threshold values therefor specific to the optic and prestored in a database, whereby the optic can be tested quickly and without personal influences, with a reliable test result.

1. A device (1) for testing a medical optic (2), such as an endoscope, a laparoscope, an arthroscope or a bronchoscope, wherein the optic (2) has a central axis extending in the longitudinal direction thereof and the optic (2) is mountable on the device (1) along the central axis, comprising:
a test image (50), a test image table (10) for supporting the test image (50), a first light source (7) for lighting the test image (50) via the optic (2) mountable thereon, an attaching device (3) for mounting the optic (2), detection means (42, 43, 45) placed on the attaching means (3) for detecting the lighted test image (50), first guide means (39) and second guide means (19) co-acting with the first guide means (39) and extending in longitudinal direction thereof for the purpose of positioning the test image table (10) along a substantially straight line relative to the attaching device (3), and a signal processing device (6) for receiving, storing and comparing detection values of the lighted test image (50) detected by the detection means (42, 43, 45) to threshold values therefor specific to the optic (2) and prestored in a database,wherein the first (39) and/or the second guide means (19) are situated parallel to and at a distance from the central axis of the optic (2), the attaching device (3) for mounting the optic (2) is adjustable relative to the test image (50) along the longitudinal direction of the optic (2), the first guide means (39) are arranged on the attaching device (3) and the second guide means (19) are arranged on the test image table (10) for relative displacement of the attaching device (3) relative to the test image (50), a servomotor (11) is adapted to displace the attaching device (3) relative to the test image (50) in the longitudinal direction of the optic (2), characterized in that the optic (2) is provided with identification elements (20) and wherein the device (1) is provided with read elements (60) for reading the identification elements (20).
