This is a series of water immersion objective lenses developed
for experiments in electrophysiology. The UW multi-coating displays
flat images with a high transmission factor up to the near infrared
region, while also achieving excellent DIC and fluorescence from the
visible range to infrared. Also available is a 60x objective with NA
1.1 and 1.5 mm working distance, making it ideal for fluorescence
imaging of brain tissue as well as other tissue and specimens.
