A high-resolution optical spectrometer with multiple diffractive optical elements operates under broadband light and enables spectral splitting with 3D diffractive optical elements. Diffractive optical elements are used to provide concentration of light as well as spectral splitting. Depending on the application, the high-resolution optical spectrometer operates with a reflection or transmission diffractive optical element. The number of operating wavelengths, spectral resolution, and operating bandwidth of diffractive optical elements are flexible depending on application.

The computer system and computer-implemented method of generating and providing skin care product recommendations to a subject, wherein the method comprises determining, by a computing device, a UV-B exposure of the subject; determining, by the computing device, a vitamin D intake due to the UV-B exposure; determining, by the computing device, a target vitamin D of the subject; and providing, by the computing device, a skin care product recommendation to the subject when the vitamin D intake due to the UV-B exposure is less than the vitamin D target of the subject.

A vehicle including: (a) a water generator configured to generate water; (b) a water storage container configured to store the water that the water generator generates; (c) an ultraviolet light emitter configured to emit ultraviolet light into the water storage container; (d) a sensor configured to detect the ultraviolet light that the ultraviolet light emitter has emitted; and (e) a human-machine interface configured to issue a notification to a user of the vehicle regarding the ultraviolet light emitter. The sensor can detect a wavelength range of the ultraviolet light that the ultraviolet light emitter has emitted. The sensor can detect an intensity of the ultraviolet light at a predetermined wavelength or wavelength range that the ultraviolet light emitter has emitted. The vehicle further comprises a controller in communication with the ultraviolet light emitter, the sensor, and the human-machine interface.

A Far UV C excimer bulb assembly including an excimer bulb, and at least two filters. The excimer bulb emits a path of light in at least two wavelengths. The at least two filters remove all wavelengths of light that are hazardous to human tissue. The at least two filters may each be placed perpendicular to the path of the light generated by the excimer bulb. The at least two filters may be a single, curved or cylindrical filter. The assembly may further include a mirror which may also be curved.

The use of photochromic pigment detection to determine UV output intensity of a UV illuminating source within a reptile cage. More specifically, photochromic pigment may be placed at a location within the cage so that it may selectively be exposed to a UV illuminating source and through a color change, identify the relative intensity of UV output.

A sensor for discriminating between wavelength regions in an electromagnetic spectrum is disclosed. The sensor comprising a substrate, a sensing element supported on a surface of the substrate, and at least one pair of terminal electrodes disposed on the substrate surface in mutually spaced apart and opposing relation, and in electrical contact with the sensing element, wherein the sensing element is responsive to electromagnetic radiation to yield a change in photocurrent measured between the terminal electrodes as a function of an intensity of the electromagnetic radiation impinging thereon, wherein a positive dependency on the intensity corresponds to a first wavelength region and a negative dependency on the intensity corresponds to a second wavelength region.

A method of monitoring light output from at least one solid-state light source involves sensing any light produced by the at least one solid-state light source and reflected, by at least one surface spaced apart from the at least one solid-state light source, to at least one reference location spaced apart from the at least one surface.
