Series NFT-1121/2135 Mini CCD Fixed Position Scanners

2) Avoiding Specular Reflection

Do not position the scanner at an angle that causes the LED illumination to be reflected directly back into the scanner. This is called specular reflection. Too much reflected light can “blind” the scanner preventing a good decode.

If the bar code label is located on a flat surface, specular reflectivity occurs between 2 to 9 degrees off perpendicular (see diagram). If the bar code label is located on a cylindrical surface, such as a test tube, the angle of specular reflection is measured tangent to the curve. If the curved surface is also moving, there may be more than one position causing specular reflection. The following diagram indicates the area to avoid:

3) Quality Bar Code Labels

The quality of the bar code label can affect the scanning performance. Poor quality labels are more difficult to decode and may result in non-reads or potential misreads. The bar code label should be printed to specifications. This means that the bars are printed within spec, with the correct widths, no ink spread, crisps edges and no voids. There should be a sufficient quiet zone on both end of the bar code label.

For best results the paper or label stock should have a matte finish to diffuse light. The print contrast signal (which is a comparison of the reflectance of the bars and the background stock) should be as high as practical.

NFT 1125, NFT 2135 specifications

Opticon NFT 2135 and NFT 1125 are two prominent examples of the innovative applications of blockchain technology in the world of digital art and collectibles. They symbolize the burgeoning trend of non-fungible tokens (NFTs) which provide verifiable ownership of unique digital items.

Opticon NFT 2135 is celebrated for its intricate design and immersive experience. It features a stunning visual representation that blends cutting-edge graphics with augmented reality elements. Users can interact with the NFT in various environments, allowing them to explore its dynamic aspects from different angles. The underlying technology leverages smart contracts on the blockchain, ensuring that ownership and transaction history are transparent and secure. Each piece is minted on a specific blockchain that supports the ERC-721 standard, empowering users with proof of authenticity and enabling interoperability across multiple platforms.

On the other hand, Opticon NFT 1125 is distinguished by its utility and community engagement features. This NFT offers holders exclusive access to in-game assets and experiences in various virtual ecosystems. The characteristic trait of NFT 1125 lies in its ability to unlock additional functionalities for its owner, such as special events, early access to drops, and voting rights in community decisions regarding future projects. This aspect of utility not only elevates the value of the NFT but also fosters a sense of belonging among collectors and enthusiasts.

Both NFTs employ advanced technologies such as blockchain analytics and decentralized finance (DeFi) functionalities. These technologies enhance user experience by providing seamless transactions and low fees while maintaining security. The growing ecosystem of marketplaces dedicated to trading NFTs further amplifies their visibility and accessibility.

In summary, Opticon NFT 2135 and NFT 1125 showcase the diverse characteristics and technological prowess of NFTs. While NFT 2135 emphasizes artistic expression and immersive interaction, NFT 1125 focuses on community involvement and utility. Together, they illustrate how NFTs can be more than just collectibles; they can serve as gateways to interactive and engaging experiences in the digital landscape. The evolution of these NFTs not only highlights the potential of blockchain technology but also paves the way for innovative future applications.
