ZWO OIII 7nm 2英寸滤镜
$399.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
ZWO OIII 7nm 2in 滤光片可帮助减少某些波长的光的传输,增加星云和夜空之间的对比度,特别是由人造光(包括汞蒸气)以及高压和低压钠蒸气灯以及由大气中的中性氧排放(即天辉)引起的不必要的自然光产生的光。
细节
名称:ZWO 窄带 7nm 滤光片套装 2in
尺寸:2英寸
厚度:5mm+2.5mm(螺纹)
螺纹:M48.5*0.75外螺纹
ZWO OIII 7nm 2in 滤光片专为星云观测而设计,可让波长为 500nm 的 7nm 带宽光通过,这对应于 OIII 发射线,从而阻挡所有其他光。将 ZWO O-III 窄带滤光片添加到您的成像系列中,将帮助您超越 RGB 成像,并帮助您在全新光线下捕捉您最喜欢的星云,无论您的天空污染程度如何!
技术数据
- 半高宽:7±0.5nm
- 精细光学抛光,确保两个表面均具有精确的 1/4 波前
- 在主要 OIII 线 500nm 处透射率约为 90%(OIII 滤光片)
- 红外波长截止700-1100nm
- 带外透过率 <0.1%,OD3(光密度)
