Are you having problems with your machine vision camera deliveries? Due to component shortages in the global marketplace, many camera manufacturers’ lead times are 3 to 6 months and some pushing more than 9 months.
We have good news. As a stocking distributor, 1stVision has over 300 cameras in stock!
IDS Imaging, Allied Vision, and Teledyne DALSA cameras
Many of the popular Sony Pregius sensors such as IMX264, IMX249, IMX265, IMX392, IMX304, IMX545 to name a few along with sensors from ON-SEMI are in stock.
We can get USB3 cameras in 3-6 weeks even if the model is not in stock.
We may be a distributor, but our technical knowledge is second to none with our sales engineers having an average of 25 years of experience in the industry. We can solve your problems and make recommendations. We’re the stocking distributor that’s big enough to stock the best cameras, and small enough to care about every image.
We’re also committed to customer education – we maintain online resources such as a Knowledge Base and a Machine Vision Blog, regularly updated to keep you informed of new technologies and product releases. Machine vision and optics are evolving fields, with new technologies constantly emerging – it pays to stay informed.
Visible to SWIR sensors that cover both the visible and short wave infrared spectrum, are now available, affordable, and well-suited for a range of imaging applications. Previously one might have needed two different sensors – and cameras – but Allied Vision’s Alvium 1800 U/C-030 and Alvium 1800 U/C-130 take advantage of Sony’s innovative InGaAs SenSWIR sensor technology to provide coverage across the visible to SWIR spectrum with the Sony IMX991.
Alvium VSWIR with MIPI CSI-2 and USB3 Vision interfaces
These Alvium 1800 VSWIR cameras can be used from 400 nm to 1700 nm, and are the smallest industrial-grade, uncooled SWIR core modules on the market. With their compact design, low power consumption, and light weight, they are the ideal solution for compact OEM systems used in embedded and machine vision applications.
The 030 models use a ¼”sensor with framerates to 223 fps, while the 130 models use a ½” sensor with framerates to 119 fps. Both are available with USB3 Vision or MIPI CSI-2 interfaces, in housed, open, or board-level configurations.

Imaging outcomes depend crucially on contrast. It is only by making a feature “pop” relative to the larger image field in which the feature lies, that the feature can be optimally identified by machine vision software.
While sensor choice, lensing, and lighting are important aspects in building machine vision solutions with effective contrast creation, effective selection and application of filters can provide additional leverage for many applications. Often overlooked or misunderstood, here we provide a first-look at machine vision filter concepts and benefits.
Before and after applying filters
In the 4 image pairs above, each left-half image was generated with the same sensor, lighting, and exposure duration as the corresponding right-half images. But the right-half images have had filters applied to reduce glare or scratch-induced scatter, separate or block certain wavelengths, for example. If your brain finds the left-half images to be difficult to discern, image processing software wouldn’t be “happy” with the left-half either!
While there are also filtering benefits in color and SWIR imaging, it is worth noting that we started above with examples shown in monochrome. Surprising to many, it can often be both more effective and less expensive to create machine vision solutions in the monochrome space – often with filters – than in color. This may seem counter-intuitive, since most humans enjoy color vision, and use if effectively when driving, judging produce quality, choosing clothing that matches our skin tone, etc. But compared to using single-sensor color cameras, monochrome single sensor cameras paired with appropriate filters:
can offer higher contrast and better resolution
provide better signal-to-noise ratio
can be narrowed to sensitivity in near-ultraviolet, visible and near-infrared spectrums
These features give monochrome cameras a significant advantage when it comes to optical character recognition and verification, barcode reading, scratch or crack detection, wavelength separation and more. Depending on your application, monochrome cameras can be three times more efficient than color cameras.
Identify red vs. blue items
Color cameras may be the first thought when separating items by color, but it can be more efficient and effective to use a monochrome camera with a color bandpass filter. As shown above, to brighten or highlight an item that is predominantly red, using a red filter to transmit only the red portion of the spectrum can be used, blocking the rest of the transmitted light. The reverse can also work, using a blue filter to pass blue wavelengths while blocking red and other wavelengths.
Here we have touched on just a few examples, to whet the appetite. We anticipate developing a Tech Brief with a more in depth treatment of filters and their applications. We partner with Midwest Optical to offer you a wide range of filters for diverse application solutions.

1stVision is pleased to announce that Allied Vision has released three fourth-generation Sony IMX sensors with Pregius S global shutter technology to its Alvium 1800 U camera series. With the new models Alvium 1800 U-511 (Sony IMX547), Alvium 1800 U-811 (Sony IMX546) and Alvium 1800 U-1242 (Sony IMX545), the Alvium camera series with USB3 interface now comprises 19 models. All cameras are available in different housing variants (closed housing, open housing, bareboard), as monochrome or color cameras, and with different lens mount options. The USB port can be located either on the back of the camera or on the left side (as seen from the sensor).
AVT Alvium housed, bareboard, and open variants
To highlight just one key point about each new camera:
Alvium U-511: First 5.1 Mpix global shutter Sony sensor for S-mount lens
Alvium U-811: Square 8 Mpix sensor ideal for round or square objects, and microscopy
Alvium U-1242: Same resolution with smaller sensor as 2nd gen IMX304
