Background technology
Current slit source device on the market much uses monochromatic burner source as light source, and color is single, and monochromater causes astigmatism by crack imaging lens due to difference, and crack Luminance Distribution is uneven, and evenly middle, both sides are sparse.Light source by during the slit arrangement of crack because hue difference causes dispersion, cause crack color inconsistent.
Summary of the invention
The astigmatism caused is differed in order to solve existing slit source device monochrome, the problem of the dispersion that hue difference causes, the invention provides slit source device, this device is synthesized by redgreenblue light source, via rotary prism 1, device such as rotary prism 2 grade obtains illuminance distribution, the slit of illumination of solid colour.There is crack color step-less adjustment, illuminance distribution, crack solid colour be feature.
Technical scheme of the present invention is: semi-transparent semi-reflecting lens (16), green light source (12), red light source (13), Hardware drive module (17) that a kind of slit source device comprises illuminator (1), condenser lens (2), rotary prism 1 (3), rotary prism 2 (4), crack slit arrangement (5), crack imaging lens (7), the blue thoroughly semi-transparent semi-reflecting lens (15) that red green is anti-, blue-light source (11), redness reveal the green color is anti-.Primary optical axis (6) and lamp source optical axis (14) are vertically intersected on illuminator (1) center.After red light source (13) and green light source (12) pass through anti-semi-transparent semi-reflecting lens (16) synthesized source of the red color that reveals the green, then be incident upon on illuminator (1) by blue thoroughly semi-transparent semi-reflecting lens (15) synthesized source that red green is anti-with blue-light source (11).Light source colour can realize step-less adjustment.Rotary prism 1 (3) is left rotation and right rotation under driving device 1 (9) controls.Rotary prism 2 (4) rotates up and down under driving device 2 (10) controls.Light source illumination bright crack slit arrangement (5) out after condenser lens (2), rotary prism 1 (3), rotary prism 2 (4).Crack slit brightness uniformity in crack slit arrangement (5).Crack imaging lens (7) injects human eye (8) by after the crack slit image in crack slit arrangement (5).
Described crack slit arrangement (5) is circular, and periphery is light tight, and only, rectangular crack slit is hollow out, light-permeable.
Described rotary prism 1 (3) left rotation and right rotation achieves slit left and right, crack brightness uniformity.
Described rotary prism 2 (4) rotates up and down and achieves the upper and lower brightness uniformity of crack slit.
The present invention has following beneficial effect: owing to taking such scheme, this light supply apparatus is by redgreenblue synthesized source, slit left and right, the crack brightness uniformity in crack slit arrangement (5) is achieved through rotary prism 1 (3) left rotation and right rotation, rotary prism 2 (4) rotates the upper and lower brightness uniformity of crack slit achieved in crack slit arrangement (5) up and down, thus by color step-less adjustment, the slit image of illuminance distribution injects human eye (8).Have crack color stepless adjustable, solve monochromatic differ cause astigmatism, solve dispersion that hue difference causes, provide brightness uniformity, the feature of the slit image of solid colour.
