Designed to accommodate standard micro and macro cuvettes, the CVH100(/M) cuvette holder can be used in fiber or free space applications. It offers two perpendicaluar optical axes with four ports for transmission and fluorescence measurements. Both optical axes (blue lines in the photo to the right) and the axis for the post mount (red in the photo to the right) have a common crossing point to allow turning of the holder while keeping the alignment to the optical axes in free space applications.

Fiber Adapter

The holder is shipped with a collimating SMA-to-SM1 fiber adapter, allowing the cuvette holder to be directly connected to fiber-based light sources, detectors, or spectrometers. The included collimating optic is fabricated from N-BK7 glass and is uncoated. Two SM1 end caps are also included so that unused ports can be covered to prevent dust from entering the optomechanical assembly.

The optional CVH100-COL SMA-to-SM1 fiber adapter with lens mount allows the user to mount an unmounted Ø1/2" collimating lens and insert it into the beam path. Use this option to optimize the fiber coupling for specific setups (e.g., for use with large core diameter multimode fibers or if a coated lense is required. The CVH100-COL ships with 2 spacer rings and a retaining ring The desired lens needs to be ordered separately.

Mounting

All ports are equipped with four M4 taps and a single bore that has internal SM1 threading for direct mounting to our lens tubes, cage system, or light sources such as our OSL1 white light source or our mounted high-power LEDs (MxxxL2 series). The CVH100 can be mounted on ½" bases as well. The black anodized aluminium coating protects the mount from corrosion in typical lab environments.

Optical Axes of the Cuvette Holder

Figure: 1
The optical axes (blue) are perpendicular with a crossing point that is mutually perpendicular with the vertical mounting axis (red). With this orientation, the alignment remains unchanged even if the holder is turned.
