The Nikon CFI Super Fluor 40×/1.30 Oil Immersion Objective is a UV-optimized high-performance oil immersion objective from Nikon’s CFI Super Fluor series — specifically engineered for superior UV tran
KEY FEATURES
- Superior UV transmission to 340nm — the defining feature of the CFI Super Fluor series; optimized for maximum light transmission at 340nm and below, enabling fura-2 (340/380nm), indo-1 (340nm), and photo-activation of caged compounds requiring deep UV excitation
- NA 1.30 oil immersion at 40× — high numerical aperture for outstanding resolution and fluorescence light collection, maximizing signal from UV-excited fluorophores where photon budget is critical
- Optimized for UV calcium indicators — specifically designed for fura-2 ratiometric calcium imaging (340/380nm excitation), indo-1 calcium imaging (340nm), and fluo-3 fluorescence in live-cell physiology workflows
- Photo-activation of caged compounds — high UV transmission enables efficient photo-uncaging of caged ATP, caged calcium, caged neurotransmitters, and other UV-activated compounds for optogenetics and cell physiology
- Infinity-corrected, M25 thread — compatible with Nikon CFI series microscopes including Eclipse Ti2, Ti, Ni, E, and FN series
- 🇯🇵 Nikon quality, made in Japan — precision optical construction for consistent, high-efficiency UV and visible light transmission
- Condition: Excellent — flawless optics — catalog number MRF01401
