Abstract: An optical filter includes: an absorption layer including a first near-infrared absorbing dye (D1), a second near-infrared absorbing dye (D2), and a transparent resin; and a reflection layer including a dielectric multilayer film. The dye (D1) and the dye (D2) are squarylium compounds satisfying following (1) to (3). (1) The dye (D1) has a maximum absorption wavelength λmax(D1) within a range of 680 to 730 nm, and the difference between a wavelength at which a transmittance is 80% on the shorter wavelength side than λmax(D1) when the concentration is adjusted such that a transmittance at λmax(D1) is 10%, and λmax(D1) is 100 nm or less. (2) The dye (D2) has a maximum absorption wavelength λmax(D2) within a range of 720 to 770 nm. (3) A value obtained by subtracting λmax(D1) from λmax(D2) is 30 nm or more and 85 nm or less.

Abstract: A side window cap is configured to cover and seal a light emitting element onto a substrate where the light emitting element is mounted. The side window cap has a cross sectional shape of an inverted recess having an upper wall portion, four side wall portions, and a lower opening. One of the four side wall portions is a window made of a transparent material. Three of the four side wall portions and the upper wall portion are made of glass ceramic. The transparent material and the glass ceramic are directly bonded.
