機器視覺濾光片

TECHSPEC® Machine Vision Filters

TECHSPEC® Machine Vision Filters


  • 針對常見LED光源使用
  • 提供多種安裝尺寸和螺紋,提高系統相容性
  • 極高且平坦的穿透率進而提供均勻照明

TECHSPEC®機器視覺濾光片專為最嚴苛的機器視覺和成像應用而設計和製造。TECHSPEC®機器視覺濾光片讓特定的紫外、可見光或紅外波長通過或截止,並提供極寬的入射角。相較於傳統濾光片,這些硬化鍍膜濾光片可出色地阻隔不需要的光,並具備更高耐用性以達到較長的使用壽命。此外,這些濾光片可用於提高圖像對比度並隔離光譜波段顏色。

技術資訊

Edmund Optics® new line of TECHSPEC® Machine Vision Filters are designed with the industry’s best performance to cost ratio in mind. With extremely sharp edge transition and flat peak transmission, users are guaranteed the optimal signal-to-noise ratio in their imaging system without losing light intensity that is critical for performance.

On average, the blocking range reaches far into the UV at 200nm and stretches out to 1200nm, which covers most of the noise and UV/IR signatures seen in conventional lamps and bulbs.

The graphs below demonstrate the performance typical to our Machine Vision Filters and other Hard Coated filters. The sharp cut-on and cut-off wavelengths are noticeably apparent, as well as transmission values that are >10% improved over traditional imaging filters on the market.
