Optical Lens and Glass materials for Optical Lens. en Mon, 01 Jun 2026 09:00:00 +0900 http://blogs.law.harvard.edu/tech/rss/ Introduction of TAFD40L-W https://www.hoya-opticalworld.com/english/news/index.html#75 We achieved lower costs by reducing the amount of expensive rare metal raw materials used.The nd, vd, color intensity, and internal transmittance at 460nm are the same as the conventional TAFD40-W. Mon, 01 Jun 2026 09:00:00 +0900 Announcement of the Start of Sales for FDS24-SW Pressed Glass. https://www.hoya-opticalworld.com/english/news/index.html#74 FDS24-SW is a glass with even better transmittance characteristics than FDS24-W, while other characteristics are the same as FDS24/FDS24-W. Mon, 01 Jun 2026 09:00:00 +0900 Introduction of CXB700 https://www.hoya-opticalworld.com/english/news/index.html#73 The CXB700 is a new near-infrared absorption filter glass that combines the features of both the CXA700 and CXD700.It achieves a good balance between visible-range transmittance and excellent near-infrared cut performance. Thu, 02 Apr 2026 09:00:00 +0900 Introduction of TAFD30L https://www.hoya-opticalworld.com/english/news/index.html#72 Cost reduction has been achieved by reducing the use of expensive rare metal raw materials.The refractive index (nd) is the same as that of the conventional TAFD30 (nd: 1.88300).It has a lower specific gravity than TAFD30, which is advantageous for reducing the weight of optical systems. Fri, 13 Mar 2026 09:00:00 +0900 Introduction of FAD61 & MC-FAD61 https://www.hoya-opticalworld.com/english/news/index.html#71 We are releasing FAD61 (nd=1.65494, vd=61.04).This glass has the same anomalous dispersion as the FCD series. Mon, 26 Jan 2026 09:00:00 +0900 Near infrared absorption (Color Compensating) Filter https://www.hoya-opticalworld.com/english/products/cfilter.html The near-infrared absorbing (color correction) filter glass is a deep blue-green (CIE color system chromaticity notation: x: 0.254-0.280, y: 0.318-0.325). Sun, 30 Nov 2025 09:00:00 +0900 Introduction of LAF50 https://www.hoya-opticalworld.com/english/news/index.html#70 We are releasing LAF50 (nd=1.60199, νd=50.21), which has extremely high anomalous dispersion in the near-infrared region. Fri, 20 Nov 2025 09:00:00 +0900 Excel Catalog Update https://www.hoya-opticalworld.com/english/news/index.html#69 The Excel catalog has been updated. Mon, 1 Sep 2025 09:00:00 +0900 Introduction of TAFD25L https://www.hoya-opticalworld.com/english/news/index.html#68 Cost reduction has been achieved by reducing the amount of expensive rare metal raw materials. nd and vd are the same as the conventional TAFD25. (nd:1.90366 νd:31.32) Low specific gravity compared to TAFD25, which is advantageous for reducing the weight of optical systems. Mon, 23 Jun 2025 09:00:00 +0900 Introduction of MC-NBFD130L https://www.hoya-opticalworld.com/english/news/index.html#67 Cost reduction has been achieved by reducing the amount of expensive rare metal raw materials. nd and vd are the same as the conventional MC-NBFD130. (nd:1.80610 νd:40.73) Tg is approximately 20°C lower than MC-NBFD130. GMO press molding temperature can be lowered. Mon, 23 Jun 2025 09:00:00 +0900
