Your camera for ophthalmological applications
Every application in ophthalmology has its individual requirements. We know how to help you find the best camera solution for your application.
The numbers for eye diseases are growing globally. Modern lifestyle and longer life expectations of people in developed countries are the main driving factors. Patients with a diagnosis of myopia or farsightedness can get better sight with glasses or lenses. Astigmatism or cataracts however sooner or later require operative therapy.
Ophthalmic equipment featuring cameras includes:
- Slit Lamp – used for standard diagnosis examining and imaging anterior and posterior segments of the eye.
- Fundus Camera – also for diagnostics; shows the back interior surface of the eye including the retina and optic disc.
- OCT, Optical Coherence Tomography, utilizes the characteristics of near infrared wavelength to image the translucent and opaque sub-surface 2-4 mm of anterior segment and retina.
- Wavefront analyzer, used to characterize eyes for corneal treatments like LASIK, where the cornea is reshaped for better vision. Requires special wavefront sensors in the camera.
- Cataract laser gives therapy to patients with astigmatism, cameras are used for monitoring the operation as with surgical microscopy.
When choosing a camera for Ophthalmic applications, the following aspects are relevant:
- Slit Lamp: USB interface for easy connection to host PC
- Fundus Camera requires excellent color reproduction and low light sensitivity, maybe near infrared wavelength for fluorescence
- OCT requires 20-50fps to mitigate eye movement during the exam, good quantum efficiency at 820-840 nm (near infrared) to go sub-surface on the retina
- Sensor resolution of 6-24 MP depending on your application
- Check if you can go with a CMOS sensor. Those are competitive compared to CCDs - at lower price and better long-term availability
The Alvium camera series has a USB3 interface and offers a large variety of CMOS sensors. Our Color Matrix feature enables excellent color reproduction according to your preferences. If you are looking to replace your current CCD camera we can offer you many CMOS alternatives in format and pixel size.
