摘要： A furniture used for appreciation, etc. of an article, comprising an antireflection film is provided, wherein the antireflection film is effective to enhance an enchantment of an article as an object to be exhibited and has high designability. A collection case 1, as an example of the furniture used for appreciation, etc. of an article, comprises a bottom member 2 for mounting an article G as an object to be exhibited, and a transparent cover 4 to enclose an article G mounted on the bottom member 2 to see through it. On a main surface side for mounting an article G of the bottom member 2 is provided with a black antireflection film 9. The antireflection film 9 is formed of a membrane made from a liquid composition having a specific composition to be a thickness of 2 μm or more and 40 μm or less by spray coating.

摘要： An optical element for reducing stray lights includes an antireflection film. Here, (A) indicates a resin component, (B) unevenness forming particles, (B1) inorganic small particles having a particle diameter (d1) of between 0.05 μm and 0.4 μm, (B2) inorganic-type large particles having a particle diameter (d2) of 2 μm or more and 6 μm or less, and (C) a diluent solvent. The antireflection film is a membrane formed of a liquid composition via spray coating to have a thickness of 2 to 40 μm. The liquid composition comprises at least (A), (B) and (C). The (B) is contained in an amount of 20 to 60% by mass in 100% by mass of a total amount of the total solid content in the composition. The (B) contains (B1) and (B2) in an amount of 90% by mass or more. A mass ratio of (B2) to (B1):1 is 1.8 or more and 3.3 or less.

摘要： Provided is a black light-shielding member, which has an excellent effect of anti-reflection that based on low glossiness and has a high blackness. A black light-shielding member including a substrate film, a resin-made light-shielding layer having a concave-convex shape formed on at least one surface of the substrate film, and a blackened layer formed on the resin-made light-shielding layer is produced. By adjusting an arithmetic mean surface roughness Ra of the surface on which the light-shielding layer and the blackened layer are formed to be 0.25 μm or more, and the maximum thickness of the blackened layer is less than the said Ra, a blackness with an L value of 12 or less is achieved.

摘要： A distance measuring device 1 capable of achieving high measurement accuracy is provided. The distance measuring device 1 comprises a LiDAR sensor unit 7 in a storage chamber 5 partitioned inside an exterior member 2. The LiDAR sensor unit 7 comprises a light emitting element 71 for emitting a detection light L1 for measuring a distance to an object, a light receiving element 73 for outputting a light-receiving signal S1 in accordance with an amount of an incident light, and a translucent cover 3 for covering the light emitting element 71 and light receiving element 73. Antireflection films 9a and 9b are provided at least on one main surface side of the translucent cover 3. The antireflection films 9a and 9b are configured by a membrane having a thickness of 2 μm or more and 40 μm or less formed from a liquid composition having a specific composition by spray coating.
