天文带通滤光片
天文带通滤光片&bull 过滤和测量来自天体的光线&bull 光度校准的理想选择&bull UBVRI 滤光片通用规格表面质量:60-40 厚度 (mm):5.00 ±0.1传输波前,RMS:λ/4平行度(弧秒):30产品介绍天文带通滤光片用于过滤和测量天文和天体发射的特定波段的光。鉴于传感器的响应,Johnson/Bessel 滤光片适合与光电倍增管一起使用,而 Kron/Cousin 滤光片则更适合与硅传感器一起使用。这两种类型的滤光片都是利用相同的紫外(U)、蓝光(B)和紫光(V)滤光片。 不过,红光(R)和红外(I)滤光片已经优化可与光电倍增管或硅CCD探测器一起使用。天文带通滤光片具有精确控制的厚度,以减少更换滤光片时常见的重新聚焦问题。技术数据订购信息Dia.
