Definitions
- the present invention relates to a collimating lens that collimates light emitted by a laser device of a laser display module, and more particularly to a collimating lens capable of suppressing chromatic aberration with respect to wavelength variation of light.
- the present invention has been made in view of the above problems, and it is an object of the present invention to provide a collimating lens which can be constituted by a single lens and has good chromatic aberration characteristics.
- FIG. 1 shows a schematic view of a laser display device using a collimator lens in the present embodiment.
- the laser display device includes a laser device 2 for emitting light, a collimator lens 1 for converting light from the laser device 2 into parallel light, and an image generating device 3 to which light collimated by the collimator lens 1 is incident; And a screen 4 on which the light emitted from the image generation device 3 is projected.
- the image generation device 3 branches the incident light based on the input signal and projects the light on the screen 4.
- the screen 4 is configured to emit light when the light is projected, and an image can be generated on the screen 4 by scanning the projection position with respect to the screen 4 by the image generation device 3.
- FIG. 3 A graph showing the relationship of ⁇ WD / f to the reciprocal of the Abbe number dd is shown in FIG. 3, and a graph showing the relationship of ⁇ WD / f to D / f when the lens thickness is D is shown in FIG.
- the graph shows the relationship of ⁇ WD / f to R1 / f when the paraxial radius of curvature of the collimator-side lens 11 is R1.
- the parameter conditions in each figure are shown in Tables 4 to 6.
