Andover Corporation現(xiàn)在將UBVRI過濾器作為標(biāo)準(zhǔn)產(chǎn)品提供。這些濾光片用于濾除和測(cè)量天文物體發(fā)出的特定光帶。
提供兩種類型:Johnson / Bessel和Kron / Cousins。Johnson / Bessell型更適合與光電倍增管一起使用,而Kron / Cousins型則更適合與硅CCD一起使用。兩種過濾器套件都可以很好地工作,但是在購買任何套件之前,先確定要使用的測(cè)量系統(tǒng)的類型很重要。
兩種濾波器類型都使用相同的U,B和V濾波器。每種類型的R&I過濾器都不同;它們與所用檢測(cè)器的響應(yīng)更好地匹配。
更換濾鏡時(shí),重新對(duì)焦始終是一個(gè)問題。Andover通過將所有過濾器研磨和拋光至非常精確的厚度來*地減少了此問題。
UBVRI過濾器有多種標(biāo)準(zhǔn)尺寸和定制尺寸。除安裝在螺紋環(huán)中的兩種尺寸外,所有其他尺寸均未安裝。
