SPPDI® Model 1.3 — US$2495.00
SPPDI Model 1.3 is comprised of a very sturdy black anodized CNC machined aluminum enclosure with a 2″ diameter Telescope Attachment attached to the SPPDI Main Port. A 3D printed Laser Attachment, a 3D printed Video Alignment Camera Attachment, and a 3D printed Instrument Port Attachment are also supplied. (These 3D printed attachments do not contribute to the structural strength of the SPPDI.) Note that the previously offered 3D printed PLA versions of the SPPDI are no longer offered.
SPPDI Model 1.3 is provided with two slits in the enclosure cover, which permit the insertion of 3″ long x 1/2″ wide x 1 mm thick black plastic light absorbers in the signal beam arm and/or the reference beam arm of the SPPDI. Insertion of the light absorber enables blocking the signal beam or reference beam without disturbing the rotational orientation and tilt of the internal polarizer tilt plates when making sensitive measurements, or when performing geometrical phase shifting.
SPPDI units are assembled and tested at our manufacturing facility as orders are received. We do occasionally have a small inventory of this product available for immediate shipment. Otherwise, delivery time is typically 5 – 6 weeks after receipt of your order. If an order cancellation is received any time prior to shipment, your payment will be promptly refunded. Please see our Warranty and Returns policy here.
An order for a SPPDI Model 1.3 may be initiated by contacting Kerry Optical Systems, LLC by email or phone. Please see our Payments page for payment instructions.
An SPPDI Model 1.3 includes:
- Pre-assembled built-in laser source with USB-A 5-volt power pigtail.
- Pre-assembled built-in NTSC-AV2 video alignment camera with USB-A power and male BNC video signal pigtails
- Battery-powered laser collimator (Li-ion battery not included)
- Foam padded carrying case
- Free shipping by ground transportation within the continental US
Note: User must supply a video signal cable terminated in a female BNC connector for connection of the video alignment camera to a user-supplied video display device. Also note that high precision reference mirrors and focal ratio conversion optics (collimating lens attachment and microscope objectives) are not included, but may be purchased separately.
Attention: For best performance, we recommend the use of an adjustable (rotatable) linear polarizing filter, to be mounted to the user’s camera lens. This will increase the interference fringe contrast. We highly recommend Hoya brand linear polarizing camera filters (type “PL”), which are available in a variety of sizes to fit different camera lenses. These are commonly available in camera stores or online.
The SPPDI Model 1.3 is a Class 1 laser product, and is inherently safe to use. However, if you are unfamiliar with the use of lasers, you are advised to read the Laser Safety section of this website.
