ソフトウェア処理前のコントラスト向上
A machine vision filter can reduce background light before the image reaches the sensor, often improving stability more than software thresholding alone.
Optofilters.com へようこそ ― 精密光学ソリューション。Optofilters.com にて OPTOStokes ブランド公式メーカーとして展開しております。
産業カメラシステムでコントラスト向上・不要光抑制・有用照明帯域分離に使用されるマシンビジョンフィルターを比較してください。
照明波長とカメラ感度にフィルターを合わせてください。モノクロシステムではコントラストとバックグラウンド除去を優先し、カラーシステムでは色バランス・IR 漏れ・レンズマウントフォーマット・環境耐久性を確認します。
OPTOStokes マシンビジョンフィルターは、産業検査・品質管理・バーコードスキャン・ロボットビジョン用途のイメージング性能を向上させます。このセクションの IR カットフィルターとバンドパスフィルターは、コントラストを改善し、グレアを低減し、Basler・FLIR などの産業カメラシステムで精密な色または波長別検出を可能にします。

A machine vision filter can reduce background light before the image reaches the sensor, often improving stability more than software thresholding alone.
Select filters around the illumination wavelength and camera response curve. IR cut, visible bandpass, and NIR pass filters solve different inspection problems.
Consider dust, angle, vibration, and lighting variation when selecting filter size, mounting, and coating durability.
Filters improve image consistency by passing useful illumination and rejecting ambient or unwanted wavelengths.
Yes. IR pass filters can reduce visible-light interference and improve contrast for selected materials and lighting conditions.
Yes. Custom diameters, thicknesses, and shapes can be supplied for camera holders, lens mounts, and OEM inspection modules.
