結露によるレンズトラブルを解決
Solves lens problems caused by condensation
従来のバスのドライブレコーダー用のカメラでは 1年～1年半で、画面が曇る現象が発生し、バス会社は頭を抱えていました。
使用しているレンズの表面が白濁し撮影に影響が出ていたのです。
Bus companies were troubled by the phenomenon of fogging of the screen of conventional cameras for bus drive recorders after a year to a year and a half.
The surface of the lens used became cloudy, which affected the filming.Bus companies were troubled by the phenomenon of fogging of the screen of conventional cameras for bus drive recorders after a year to a year and a half.

原因は、結露によるコーティング劣化
Cause: Coating deterioration due to condensation
ドライブレコーダーは天候により発生した結露でレンズ表面に水滴がつき、それが乾くという事象を繰り返します。
そしてレンズ表面のコーティングが劣化し、レンズ表面が白濁した状態になるのです。
これは「白ヤケ」とも言われます。
The drive recorder repeats the process of water droplets on the lens surface due to condensation caused by weather conditions, and then dries up.
The coating on the lens surface then deteriorates and the lens surface becomes cloudy.
This is also referred to as "white burn.The drive recorder repeats the process of water droplets on the lens surface due to condensation caused by weather conditions, and then dries up.

結露が発生しづらいコーティングを発見し、新しい「車載用レンズ」が完成
Discovery of a coating that prevents condensation from forming, resulting in a new "lens for in-vehicle use
一般的なレンズは車載への搭載を想定していないため、長時間環境試験を行いながら結露しにくいコーティングを模索しました。
そして、成果が出たコーティングを車載カメラのレンズに施し「車載用レンズ」が完成しました。
結果、そのレンズを採用後は画面が曇る現状は発生しなくなり、安全な運転、バス会社の管理に大きく貢献できたのです。
Since general lenses are not designed for in-vehicle use, we sought a coating that would resist condensation while conducting environmental tests over an extended period of time.
We then applied the successful coating to the lens of an in-vehicle camera and completed the "lens for in-vehicle use.
As a result, after the lens was adopted, fogging of the screen no longer occurred, contributing greatly to safe driving and bus company management.Since general lenses are not designed for in-vehicle use, we sought a coating that would resist condensation while conducting environmental tests over an extended period of time.
