High-resolution IR imaging is used mostly to reveal preparatory drawings and/or alterations in paintings on canvas. To some limits it may be used for identification of pigments. It can also be used to differentiate iron galling from carbon-based inks.

Apollo is the new standard in infrared reflectography. Following in the footsteps of the world-renowned Osiris Camera, Apollo uses an internal scanning mechanism to produce high-quality, high-resolution infrared reflectograms with an unparalleled level of clarity and detail, boasting over 65,000 grey levels. These images can be used to study various aspects of a painting, from changes to underdrawings and pentimenti in the work to underpainting and transmission of pigments at different wavelengths when using our filter set. If you are looking to create detailed, high-quality, high-resolution infrared images suitable for publication, Apollo is the IR camera system for you. In contrast to Osiris’s line sensor, Apollo uses an area sensor to capture thousands of tiles that are all automatically and seamlessly stitched using our new advanced imaging software. This latest infrared camera represents a huge improvement in dynamic range, capturing fine details even across demanding light and dark areas of your subject. An adjustable histogram within the software allows you to get the most out of this dynamic range, both when viewing an infrared reflectogram, and to help you get the most out of your lighting when setting up. A variety of pre-set exposure times mean you can adapt your settings to your subject and respond to the demands of your subject. This is particularly good news if you plan on making use of the Opus Instruments Filter Set that allows you to study the transmission of pigments at different bands within the spectral sensitivity of the camera.
