Multiphoton Objectives and the FVMPE-RS

Multiphoton Excitation Objectives

Engineered to achieve optimum performance with multiphoton excitation imaging (MPE), A Line MPE objectives enable high-precision imaging of biological specimens to a depth of up to 8 mm for in vivo and transparent samples.

Deep Mouse Brain Imaging

Deep in vivo, multiphoton brain imaging and optogenetics at high resolution require objectives that have high transmission of infrared (IR) light, a high numerical aperture (NA), and the ability to correct for the depth and scattering of tissue. This objective delivers ultra-broad IR transmission, enabling optogenetic stimulation with visible light down to 400 nm and IR imaging or stimulation beyond 1600 nm. The correction collar reduces the excitation volume, enabling stimulation of single cells or dendritic spines. Combined with the powerful and precise scanning capabilities of the FVMPE–RS microscope, the XLPLN25XWMP2 objective is the right tool for high-precision multiphoton imaging.

Deep Observation of Fixed Transparent Specimens with Multiphoton Objectives to a Depth of 8 mm

Our multiphoton objectives help facilitate breakthrough research on brain function and other vital organs by enabling researchers to see as deep as 8 mm without slicing. The XLPLN25XSVMP2 and XLSLPLN25XSVMP2 objectives support many clearing reagents.

Whole Mouse Brain Imaging (XLPLN10XSVMP)

The objectives offer a wide field of view with 10X magnification, single-cell resolution with an NA of 1.0, and observations down to 8 mm. The objectives match a wide range of clearing reagent refractive indices (ne: 1.33 to 1.52).

High-Resolution Deep Brain Imaging of a ScaleS-Treated Mouse Brain (XLSLPLN25XGMP)

With a numerical aperture of 1.0 and an 8 mm working distance, the objectives enable deep, high-resolution imaging with a refractive index that matches that of many clearing reagents (ne: 1.41 to 1.52).
