Description

Предметом изобретени   вл етс  установка дл  фотометрировани  светооптических систем телецентрическим методом.The subject of the invention is an installation for photometry of optical optical systems by a telecentric method.

Особенностью предлагаемой установки  вл етс  применение параболического отражател , в фокусе которого расположена диафрагма фотометрической камеры с помеп1,енным внутри нее менисковым светофильтром и фотоэлементом .A feature of the proposed installation is the use of a parabolic reflector, the focus of which is the diaphragm of a photometric camera with a filter 1, a meniscus light filter and a photocell inside it.

Схема установки показана на черте ;е.The installation diagram is shown in the drawing; e.

Световой поток от испытуемого источника /направл етс  ка приемное параболическое зеркало 2, собираетс  в фокусе последнего, проходит через расположенную там перпендикул рно оптической оси диафрагму 3 и через менисковый светофильтр 4 попадает далее на фотоэлемент о, коррегированHbiii на чувствительность среднего глаза. ВозникаюП1,ий при этом фототок регистрируетс  иидикатором 6.The light flux from the source being tested / directed to the receiving parabolic mirror 2, collected at the focus of the latter, passes through the diaphragm 3 located there perpendicular to the optical axis, and then passes through the meniscus filter 4 into the sensitivity of the middle eye, corrected by Hbiii. P1 arises, while the photocurrent is recorded by the indicator 6.
