Carl Zeiss Axio Scan 7 slide scanner allows high-throughput automated imaging of large numbers of slides loaded automatically from a magazine with the capacity of 100 slides. A sensitive CMOS camera allows detecting weak fluorescence while a colour camera is suitable for transmitted light imaging of histologically stained samples.
Available techniques:
- Transmitted light imaging
- Circular and linear polaristion contrast in transmitted light imaging
- Widefield multi-channel fluorescence imaging
- Automated scanning of large numbers of slides
Objectives:
- Fluar 5x/0.25 dry, FWD 12.5 mm, CG 0.17 mm
- Plan Apochromat 10x/0.45 dry, FWD 2.1 mm, CG 0.17 mm
- Plan Apochromat 20x/0.8 dry, FWD 0.55 mm, CG 0.17 mm
- Plan Neofluar 20x/0.5 dry, FWD 2.0 mm, CG 0.17 mm, for polarised light
- Plan Apochromat 40x/0.95 dry, FWD 0.25 mm, CG 0.13 - 0.21 mm
[FWD = free working distance, CG = cover glass]
