Andover Corporation現在將UBVRI濾光片作為標準產品提供。這些濾光片用于濾除和測量天文物體發出的特定光帶。
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，先確定要使用的測量系統的類型很重要。
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；它們與所用檢測器的響應更好地匹配。
更換濾鏡時，重新對焦始終是一個問題。 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過濾器有多種標準尺寸和定制尺寸。除安裝在螺紋環中的兩種尺寸外，所有其他尺寸均未安裝。
