To generate light with high color rendering properties while suppressing an occurrence of unevenness. The present disclosure provides a medical system () including: a medical device () provided with an imaging unit configured to image an observation object; and a light source apparatus () configured to generate light to irradiate the observation object, wherein the light source apparatus has: a narrow-band light source () configured to emit narrow-band light of which a wavelength width is a narrow band; a wide-band light source () configured to emit wide-band light of which the wavelength width is wider than the narrow-band light; a combining unit () configured to combine the narrow-band light and the wide-band light; and an emission angle converting unit () configured to convert an emission angle of the narrow-band light.

Medical system, medical light source apparatus, and method in medical light source apparatus

An optical device includes: a light synthesis prism that synthesizes incident light beams which are incident to a plurality of incidence surfaces and outputs the synthesized light beams; a light modulation unit that includes an optical compensation element and a reflective light modulation device; and a fixing member that fixes a reflective polarization element and the light modulation unit to the light synthesis prism so as to correspond to one of the incidence surfaces, wherein the light modulation unit includes a light blocking member that blocks light from reaching the light modulation unit and limits light with which the optical compensation element and the reflective light modulation device are irradiated, to light passing an aperture portion; and a heat insulating member that comes into contact with the light blocking member and the fixing member.

Optical device and projection device using the optical device which reduce registration shift caused by heat

An image display device includes: an optical modulator; and an optical compensation element configured to cancel out phase difference generated within the optical modulator; wherein the optical compensation element is installed in a state in which the brightness of a projected image corresponding to a region having relatively great phase difference within the optical modulator becomes a minimal value, at the minimum driving voltage to be applied to the optical modulator.
