Envisu SD-OCT
Formerly Bioptigen & Leica
The Envisu Product Line
The Envisu product line includes a range of systems, each with a different spectrometer and hand held probe configuration. Each system has specific applications that designed to tackle specific imaging goals, but all systems are extensible and cover OCT imaging for all animal species.
R2200
OCT-only system ideal for small animals with an imaging depth of 1.7mm in tissue, extensible to large animals with additional retinal and telecentric lenses.
R2310
OCT + Color Video Alignment Camera with an imaging depth of 2.5mm in tissue and optical axial resolution of 2.4µm, it is ideal for deeper imaging in larger species.
R2210
OCT + Color Video Alignment Camera ideal for small animals with 1.7mm imaging depth in tissue, extensible to large animals with additional retinal and telecentric lenses.
R4300
OCT-only deep imaging system features 5.4mm imaging depth in tissue with 2.6µm optical axial resolution. Whole mouse eye biometry and large animal anterior segment are common applications.
R2300
OCT-only system with an imaging depth of 2.5mm in tissue and optical axial resolution of 2.4µm, ideal for deeper imaging in larger species.
R4310
OCT + Color Video Alignment Camera deep imaging system features 5.4mm imaging depth in tissue with 2.6µm optical axial resolution. Whole mouse eye biometry and large animal anterior segment are common applications.
R4110
The finest resolution OCT + Color Video Alignment Camera with the "XHR" NKT White Light Laser. 0.8µm axial pixel resolution in tissue, 2.3mm scan depth (1.6 mm in tissue), and 2.4µm optical axial resolution. Ideal for imaging mouse Schlemm's Canal and providing superior resolution of retinal layers.
Gen4 Envisu
The Envisu R2210 Gen4 Handheld OCT system is the animal research world's workhorse.
​
Tried and true, the R2210 offers a live color fundus alignment camera built into the OCT scan head for easy orientation and alignment, various imaging stages specific to each animal species, fully customizable scan parameters, and reloadable protocols.
​
Extensible to imaging any species with dedicated bore lenses, you can take this system from small to large animal imaging in an instant.

Lighter and Cheaper
The Gen3 handheld probe head is compatible with three Telecentric lenses, each with a different Numerical Aperture for a range of depth-of-focus and lateral resolution of the rodent anterior chamber, cornea, and schlemm’s canal.
​
The 12TELE is best for anterior imaging in mice and for tissue explants.
​
Use the Mouse Retina Bore to image small eyes from zebrafish to mice.
​
Use the Rabbit and General Retina Bores for larger eyes from rabbit to canine.
