BHK推出新款锌灯/214nm紫外线灯

美国BHK公司推出新款Analamps®10-K锌灯

BHK推出特殊技术处理的10,000小时最长寿命的低压Analamps®10-K锌灯。低压锌和镉灯是极短波长紫外辐射区的主要光源。这种灯发出的强光谱线在锌213.9 nm和镉228.8 nm。这种灯是在双孔灯体和发热区域使用特殊真空护套。这种护套将带有锌或镉弧的灯体与外部环境隔离。这给了灯体优良的温度稳定性，而产生很低的噪音和不受外部温度波动影响的稳定灯亮度。灯发出的光辉来自于位于灯相对两侧的两个端口。这种灯辉可以两个端口同时使用，可以是一个单一端口，也可以弧的任何端口。这种灯可以用侧向或轴向灯线结构以及硅树脂或Delrin灯座。

BYK Zinc and Cadmium lamps

Low pressure Zinc and Cadmium lamps are major sources of extreme short wave UV radiation. They produce a strong spectral line source at 213.9 nm for Zinc and 228.8 nm for Cadmium. Zinc and Cadmium Lamps are commonly used in air pollution monitoring and sulphur dioxide(SO2) detection systems.

Features

• Short Wave UV Radiation

• High Light Output Stability

• Efficient Two Port Output

• Low Noise

• Available with 10000 Hour Lifetime

• Custom Designs and Configurations

• Special Vacuum Jacket Construction

• High Frequency Power Supplies Available

  
  

The lamps are constructed using a special vacuum jacket around the double bore lamp body and heat shield. The jacket isolates the lamp body, with the zinc or cadmium arc, from the external environment. This gives the lamp body excellent temperature stability resulting in very low noise and steady lamp intensity that is relatively independent of external temperature fluctuations.
The radiance from the lamp comes from two ports located on opposite sides of the lamp. This radiance can be used from both ports simultaneously, from a single port, and from any portion of the arc.
Lamps are available with either radial or axial lead wire configurations and Silicon or Delrin end caps. Choose from a number of lead wire and lead termination options as shown in the Datasheet. For OEM applications BHK can design custom lead and connector terminations.

Long life 10-K Zinc Lamps offer the same high performance as our standard Zinc Lamps, but special processing allows for longer lifetimes. Warranties of 2,500 or 10,000 hours are offered, depending on your application / use.
